<ch_title>Core improvements</ch_title>
-<ul>
-<li>JMeter now provides a new BackendListener implementation that interfaces InfluxDB.
-<figure width="813" height="407" image="changes/3.2/backend_influxdb.png"></figure>
-This implementation sends data using Asynchronous HTTP calls to InfluxDB through its <a href="https://docs.influxdata.com/influxdb/v1.2/guides/writing_data/">HTTP API</a>
-and give you the following graphs with annotations:
-<figure width="934" height="399" image="backend_listener_influxdb_graph.png"></figure>
-</li>
-<li>DNS Cache Manager now has a table to allow static host resolution.
-<figure width="803" height="561" image="changes/3.2/dns_cache_manager_static_hosts.png"></figure>
-</li>
-<li>JMS Publisher and Subscriber now allow reconnection on error with pause.
-<figure width="852" height="738" image="changes/3.2/jms_publisher_reconnect.png"></figure>
-<figure width="716" height="538" image="changes/3.2/jms_subscriber_reconnect_pause.png"></figure>
-</li>
-<li>Variables in JMS Publisher are now supported for all types of messages. Add the encoding type of the file to parse its content</li>
-<figure width="750" height="743" image="changes/3.2/jms_subscriber_content_encoding.png"></figure>
-<li>XPath Extractor now allows extraction randomly, by index or for all matches.
-<figure width="823" height="348" image="changes/3.2/xpath_extractor_matchno.png"></figure>
-</li>
-<li>Response Assertion now allows to work on Request Header, provides a "OR" combination and has a better cell renderer
-<figure width="1053" height="329" image="changes/3.2/response_assertion.png"></figure>
-</li>
-<li>JMeter now uses Oracle Nashorn Javascript engine instead of Rhino. This provides a faster execution of Javascript.</li>
-<li>HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default</li>
-<li>Embedded resources download in CSS has been improved to avoid useless repetitive parsing to find the resources</li>
-<li>An important work on code quality and code coverage with tests has been done since Sonar has been setup on the project.
-You can see Sonar report <a href="https://builds.apache.org/analysis/overview?id=12927" >here</a>.
-</li>
-</ul>
<ch_title>UX improvements</ch_title>
-<ul>
-<li>When running a Test, GUI is now more responsive and less impacting on memory usage thanks to a limitation on the number of Sample Results
-listeners hold and a rework of the way GUI is updated</li>
-<li>HTTP Request GUI has been simplified and provides more place for parameters and body.
-<figure width="848" height="475" image="changes/3.2/http_request.png"></figure>
-</li>
-<li>HTTP(S) Test Script Recorder has been simplified and clarified.
-<figure width="1023" height="494" image="changes/3.2/http_recorder_1.png"></figure>
-<figure width="1021" height="711" image="changes/3.2/http_recorder_2.png"></figure>
-</li>
-<li>A <code>replace</code> feature has been added to Search feature to allow replacement in some elements.
-<figure width="459" height="196" image="changes/3.2/search_replace.png"></figure>
-</li>
-<li>View Results Tree now provides a more up to date Browser renderer which requires JavaFX.</li>
-<li>You can now add through a contextual menu think times, this will add think times between samplers and Transaction Controllers
- of selected node.
- <figure width="326" height="430" image="changes/3.2/menu_add_think_times.png"></figure>
- </li>
-<li>You can now apply a naming policy to children of a Transaction Controller. A default policy exists but you can implement your own
- through <code><a href="./api/org/apache/jmeter/gui/action/TreeNodeNamingPolicy.html" >org.apache.jmeter.gui.action.TreeNodeNamingPolicy</a></code>
- and configuring property <code>naming_policy.impl</code>
-<figure width="327" height="518" image="changes/3.2/menu_apply_naming_policy.png"></figure>
-</li>
-<li>Sorting per column has been added to View Results in Table, Summary Report, Aggregate Report and Aggregate Graph elements.
-<figure width="1065" height="369" image="changes/3.2/sorting.png"></figure>
-</li>
-</ul>
<ch_title>Report/Dashboard improvements</ch_title>
-<ul>
-<li>
-Statistics have been reorganized to clarify report:
-<figure width="1548" height="366" image="dashboard/report_statistics.png"></figure>
-</li>
-<li>
-It is now possible to customize APDEX thresholds per transaction based on regular expression or sample name.

-than default ones (500 and 1500 for satisfied and tolerated thresholds) declared:
-<source>
-jmeter.reportgenerator.apdex_satisfied_threshold=500
-jmeter.reportgenerator.apdex_tolerated_threshold=1500
-jmeter.reportgenerator.apdex_per_transaction=sample(\\d+):1000|2000;\
- sampleA:3000|4000;\
- scenarioB:5000|6000
-</source>
-</li>
-</ul>
<ch_title>Documentation improvements</ch_title>
-<ul>
-<li>PDF Documentations have been migrated and updated to HTML user manual</li>
-</ul>
<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
-<ul>
- <li>JMeter requires now at least a Java 8 version to run.</li>
- <li>JMeter logging has been migrated to SLF4J and Log4j 2, this involves changes in the way configuration is done. JMeter now relies on standard
- <a href="https://logging.apache.org/log4j/2.x/manual/configuration.html">Log4j 2 configuration</a> in file <code>log4j2.xml</code>
- See <code>Logging changes</code> section below for further details.
- </li>
- <li>The following jars have been removed after migration from LogKit to SLF4J (see <bugzilla>60589</bugzilla>):
- <ul>
- <li>ApacheJMeter_slf4j_logkit.jar</li>
- <li>avalon-framework-4.1.4.jar</li>
- <li>avalon-framework-4.1.4.jar</li>
- <li>commons-logging-1.2.jar</li>
- <li>excalibur-logger-1.1.jar</li>
- <li>logkit-2.0.jar</li>
- </ul>
- </li>
- <li>The <code>commons-httpclient-3.1.jar</code> has been removed after drop of HC3.1 support(see <bugzilla>60727</bugzilla>)</li>
- <li>JMeter now sets through <code>-Djava.security.egd=file:/dev/urandom</code> the algorithm for secure random</li>
- <li>Process Sampler now returns error code 500 when an error occurs. It previously returned an empty value.</li>
- <li>In <code>org.apache.jmeter.protocol.http.sampler.HTTPHCAbstractImpl</code> two protected static fields (<code>localhost</code> and <code>nonProxyHostSuffixSize</code>) have been renamed to (<code>LOCALHOST</code> and <code>NON_PROXY_HOST_SUFFIX_SIZE</code>)
- to follow static fields naming convention</li>
- <li>JMeter now uses by default Oracle Nashorn engine instead of Mozilla Rhino for better performances. This should not have an impact unless
- you use some advanced features. You can revert back to Rhino by settings property <code>javascript.use_rhino=true</code>.
- You can read this <a href="https://wiki.openjdk.java.net/display/Nashorn/Rhino+Migration+Guide">migration guide</a> for more details on Nashorn. See <bugzilla>60672</bugzilla></li>
- <li><bug>60729</bug>The Random Variable Config Element now allows minimum==maximum. Previous versions logged an error when minimum==maximum and did not set the configured variable.</li>
- <li><bug>60730</bug>The JSON PostProcessor now sets the <code>_ALL</code> variable (assuming <code>Compute concatenation var</code> was checked)
- even if the JSON path matches only once. Previous versions did not set the <code>_ALL</code> variable in this case.</li>
-</ul>
-
<h3>Removed elements or functions</h3>
-<ul>
- <li>SOAP/XML-RPC Request has been removed as part of <bugzilla>60727</bugzilla>. Use HTTP Request element as a replacement.
- See <a href="./build-ws-test-plan.html" >Building a WebService Test Plan</a></li>
- <li><bug>60423</bug>Drop Monitor Results listener </li>
- <li>Drop deprecated class <code>org.apache.jmeter.protocol.system.NativeCommand</code></li>
- <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.config.gui.MultipartUrlConfigGui</code></li>
- <li>Drop deprecated class <code>org.apache.jmeter.testelement.TestListener</code></li>
- <li>Drop deprecated class <code>org.apache.jmeter.reporters.FileReporter</code></li>
- <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.modifier.UserSequence</code></li>
- <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.parser.HTMLParseError</code></li>
- <li>Drop unused methods <code>org.apache.jmeter.protocol.http.control.HeaderManager#getSOAPHeader</code>
- and <code>org.apache.jmeter.protocol.http.control.HeaderManager#setSOAPHeader(Object)</code>
- </li>
- <li><code>org.apache.jmeter.protocol.http.util.Base64Encode</code> has been deprecated, you can use <code>java.util.Base64</code> as a replacement</li>
-</ul>
<h3>Logging changes</h3>
-<p>
- JMeter logging has been migrated to SLF4J and Log4j 2.
- This affects logging configuration and 3<sup>rd</sup> party plugins (if they use JMeter logging).
- The following sections describe what changes need to be made.
-</p>
-
-<h4>Setting the logging level and log file</h4>
-<p>
- The default logging level can be changed on the command-line using the <code>-L</code> parameter.
- Likewise the <code>-l</code> parameter can be used to change the name of the log file.
- However the <code>log_level</code> properties no longer work.
-</p>
-<p>
- The default logging levels and file name are defined in the <code>log4j2.xml</code> configuration file
- in the launch directory (usually <code>JMETER_HOME/bin</code>)
-</p>
-<p>
- <note>If you need to change the level programmatically from Groovy code or Beanshell, you need to do the following:
- <source>
- import org.apache.logging.log4j.core.config.Configurator;
- ⋮
- final String loggerName = te.getClass().getName(); // te being a JMeter class
- Configurator.setAllLevels(loggerName, Level.DEBUG);
- </source>
- </note>
-</p>
-<h4>Changes to 3<sup>rd</sup> party plugin logging</h4>
-<p>
- <note>3rd party plugins should migrate their logging code from logkit to slf4j. This is fairly easy and can be done by replacing:
- <source>
- import org.apache.jorphan.logging.LoggingManager;
- import org.apache.log.Logger;
- ⋮
- private static final Logger log = LoggingManager.getLoggerForClass();
- </source>
- By:
- <source>
- import org.slf4j.Logger;
- import org.slf4j.LoggerFactory;
- ⋮
- private static final Logger log = LoggerFactory.getLogger(YourClassName.class);
- </source>
- </note>
-</p>

+JMeter now requires Java 8. Ensure you use the most up to date version.
+</p>
+<p>
+JMeter logging has been migrated to SLF4J and Log4j 2.
+This affects configuration and 3<sup>rd</sup> party plugins, see below <b>"Logging changes"</b>.
+</p>
+<ch_title>Core improvements</ch_title>
+<ul>
+<li>JMeter now provides a new BackendListener implementation that interfaces InfluxDB.
+<figure width="813" height="407" image="changes/3.2/backend_influxdb.png"></figure>
+This implementation sends data using Asynchronous HTTP calls to InfluxDB through its <a href="https://docs.influxdata.com/influxdb/v1.2/guides/writing_data/">HTTP API</a>
+and give you the following graphs with annotations:
+<figure width="934" height="399" image="backend_listener_influxdb_graph.png"></figure>
+</li>
+<li>DNS Cache Manager now has a table to allow static host resolution.
+<figure width="803" height="561" image="changes/3.2/dns_cache_manager_static_hosts.png"></figure>
+</li>
+<li>JMS Publisher and Subscriber now allow reconnection on error with pause.
+<figure width="852" height="738" image="changes/3.2/jms_publisher_reconnect.png"></figure>
+<figure width="716" height="538" image="changes/3.2/jms_subscriber_reconnect_pause.png"></figure>
+</li>
+<li>Variables in JMS Publisher are now supported for all types of messages. Add the encoding type of the file to parse its content</li>
+<figure width="750" height="743" image="changes/3.2/jms_subscriber_content_encoding.png"></figure>
+<li>XPath Extractor now allows extraction randomly, by index or for all matches.
+<figure width="823" height="348" image="changes/3.2/xpath_extractor_matchno.png"></figure>
+</li>
+<li>Response Assertion now allows to work on Request Header, provides a "OR" combination and has a better cell renderer
+<figure width="1053" height="329" image="changes/3.2/response_assertion.png"></figure>
+</li>
+<li>JMeter now uses Oracle Nashorn Javascript engine instead of Rhino. This provides a faster execution of Javascript.</li>
+<li>HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default</li>
+<li>Embedded resources download in CSS has been improved to avoid useless repetitive parsing to find the resources</li>
+<li>An important work on code quality and code coverage with tests has been done since Sonar has been setup on the project.
+You can see Sonar report <a href="https://builds.apache.org/analysis/overview?id=12927" >here</a>.
+</li>
+</ul>
+
+<ch_title>UX improvements</ch_title>
+<ul>
+<li>When running a Test, GUI is now more responsive and less impacting on memory usage thanks to a limitation on the number of Sample Results
+listeners hold and a rework of the way GUI is updated</li>
+<li>HTTP Request GUI has been simplified and provides more place for parameters and body.
+<figure width="848" height="475" image="changes/3.2/http_request.png"></figure>
+</li>
+<li>HTTP(S) Test Script Recorder has been simplified and clarified.
+<figure width="1023" height="494" image="changes/3.2/http_recorder_1.png"></figure>
+<figure width="1021" height="711" image="changes/3.2/http_recorder_2.png"></figure>
+</li>
+<li>A <code>replace</code> feature has been added to Search feature to allow replacement in some elements.
+<figure width="459" height="196" image="changes/3.2/search_replace.png"></figure>
+</li>
+<li>View Results Tree now provides a more up to date Browser renderer which requires JavaFX.</li>
+<li>You can now add through a contextual menu think times, this will add think times between samplers and Transaction Controllers
+ of selected node.
+ <figure width="326" height="430" image="changes/3.2/menu_add_think_times.png"></figure>
+ </li>
+<li>You can now apply a naming policy to children of a Transaction Controller. A default policy exists but you can implement your own
+ through <code><a href="./api/org/apache/jmeter/gui/action/TreeNodeNamingPolicy.html" >org.apache.jmeter.gui.action.TreeNodeNamingPolicy</a></code>
+ and configuring property <code>naming_policy.impl</code>
+<figure width="327" height="518" image="changes/3.2/menu_apply_naming_policy.png"></figure>
+</li>
+<li>Sorting per column has been added to View Results in Table, Summary Report, Aggregate Report and Aggregate Graph elements.
+<figure width="1065" height="369" image="changes/3.2/sorting.png"></figure>
+</li>
+</ul>
+
+<ch_title>Report/Dashboard improvements</ch_title>
+<ul>
+<li>
+Statistics have been reorganized to clarify report:
+<figure width="1548" height="366" image="dashboard/report_statistics.png"></figure>
+</li>
+<li>
+It is now possible to customize APDEX thresholds per transaction based on regular expression or sample name.
+The below example will apply different thresholds for samples sample(\\d+), sampleA and scenarioB
+than default ones (500 and 1500 for satisfied and tolerated thresholds) declared:
+<source>
+jmeter.reportgenerator.apdex_satisfied_threshold=500
+jmeter.reportgenerator.apdex_tolerated_threshold=1500
+jmeter.reportgenerator.apdex_per_transaction=sample(\\d+):1000|2000;\

+
+<ch_section>Incompatible changes</ch_section>
+
+<ul>
+ <li>JMeter requires now at least a Java 8 version to run.</li>
+ <li>JMeter logging has been migrated to SLF4J and Log4j 2, this involves changes in the way configuration is done. JMeter now relies on standard
+ <a href="https://logging.apache.org/log4j/2.x/manual/configuration.html">Log4j 2 configuration</a> in file <code>log4j2.xml</code>
+ See <code>Logging changes</code> section below for further details.
+ </li>
+ <li>The following jars have been removed after migration from LogKit to SLF4J (see <bugzilla>60589</bugzilla>):
+ <ul>
+ <li>ApacheJMeter_slf4j_logkit.jar</li>
+ <li>avalon-framework-4.1.4.jar</li>
+ <li>avalon-framework-4.1.4.jar</li>
+ <li>commons-logging-1.2.jar</li>
+ <li>excalibur-logger-1.1.jar</li>
+ <li>logkit-2.0.jar</li>
+ </ul>
+ </li>
+ <li>The <code>commons-httpclient-3.1.jar</code> has been removed after drop of HC3.1 support(see <bugzilla>60727</bugzilla>)</li>
+ <li>JMeter now sets through <code>-Djava.security.egd=file:/dev/urandom</code> the algorithm for secure random</li>
+ <li>Process Sampler now returns error code 500 when an error occurs. It previously returned an empty value.</li>
+ <li>In <code>org.apache.jmeter.protocol.http.sampler.HTTPHCAbstractImpl</code> two protected static fields (<code>localhost</code> and <code>nonProxyHostSuffixSize</code>) have been renamed to (<code>LOCALHOST</code> and <code>NON_PROXY_HOST_SUFFIX_SIZE</code>)
+ to follow static fields naming convention</li>
+ <li>JMeter now uses by default Oracle Nashorn engine instead of Mozilla Rhino for better performances. This should not have an impact unless
+ you use some advanced features. You can revert back to Rhino by settings property <code>javascript.use_rhino=true</code>.
+ You can read this <a href="https://wiki.openjdk.java.net/display/Nashorn/Rhino+Migration+Guide">migration guide</a> for more details on Nashorn. See <bugzilla>60672</bugzilla></li>
+ <li><bug>60729</bug>The Random Variable Config Element now allows minimum==maximum. Previous versions logged an error when minimum==maximum and did not set the configured variable.</li>
+ <li><bug>60730</bug>The JSON PostProcessor now sets the <code>_ALL</code> variable (assuming <code>Compute concatenation var</code> was checked)
+ even if the JSON path matches only once. Previous versions did not set the <code>_ALL</code> variable in this case.</li>
+</ul>
+
+<h3>Removed elements or functions</h3>
+<ul>
+ <li>SOAP/XML-RPC Request has been removed as part of <bugzilla>60727</bugzilla>. Use HTTP Request element as a replacement.
+ See <a href="./build-ws-test-plan.html" >Building a WebService Test Plan</a></li>
+ <li><bug>60423</bug>Drop Monitor Results listener </li>
+ <li>Drop deprecated class <code>org.apache.jmeter.protocol.system.NativeCommand</code></li>
+ <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.config.gui.MultipartUrlConfigGui</code></li>
+ <li>Drop deprecated class <code>org.apache.jmeter.testelement.TestListener</code></li>
+ <li>Drop deprecated class <code>org.apache.jmeter.reporters.FileReporter</code></li>
+ <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.modifier.UserSequence</code></li>
+ <li>Drop deprecated class <code>org.apache.jmeter.protocol.http.parser.HTMLParseError</code></li>
+ <li>Drop unused methods <code>org.apache.jmeter.protocol.http.control.HeaderManager#getSOAPHeader</code>
+ and <code>org.apache.jmeter.protocol.http.control.HeaderManager#setSOAPHeader(Object)</code>
+ </li>
+ <li><code>org.apache.jmeter.protocol.http.util.Base64Encode</code> has been deprecated, you can use <code>java.util.Base64</code> as a replacement</li>
+</ul>
+
+<h3>Logging changes</h3>
+<p>
+ JMeter logging has been migrated to SLF4J and Log4j 2.
+ This affects logging configuration and 3<sup>rd</sup> party plugins (if they use JMeter logging).
+ The following sections describe what changes need to be made.
+</p>
+
+<h4>Setting the logging level and log file</h4>
+<p>
+ The default logging level can be changed on the command-line using the <code>-L</code> parameter.
+ Likewise the <code>-l</code> parameter can be used to change the name of the log file.
+ However the <code>log_level</code> properties no longer work.
+</p>
+<p>
+ The default logging levels and file name are defined in the <code>log4j2.xml</code> configuration file
+ in the launch directory (usually <code>JMETER_HOME/bin</code>)
+</p>
+<p>
+ <note>If you need to change the level programmatically from Groovy code or Beanshell, you need to do the following:
+ <source>
+ import org.apache.logging.log4j.core.config.Configurator;
+ ⋮
+ final String loggerName = te.getClass().getName(); // te being a JMeter class
+ Configurator.setAllLevels(loggerName, Level.DEBUG);
+ </source>
+ </note>
+</p>
+
+<h4>Changes to 3<sup>rd</sup> party plugin logging</h4>
+<p>
+ <note>3rd party plugins should migrate their logging code from logkit to slf4j. This is fairly easy and can be done by replacing:
+ <source>
+ import org.apache.jorphan.logging.LoggingManager;
+ import org.apache.log.Logger;
+ ⋮
+ private static final Logger log = LoggingManager.getLoggerForClass();
+ </source>
+ By:
+ <source>
+ import org.slf4j.Logger;
+ import org.slf4j.LoggerFactory;
+ ⋮
+ private static final Logger log = LoggerFactory.getLogger(YourClassName.class);
+ </source>
+ </note>
+</p>

+ <!-- =================== Known bugs or issues related to JAVA Bugs =================== -->
+
+<ch_section>Known problems and workarounds</ch_section>
+<ul>
+<li>View Results Tree may freeze rendering large response particularly if this response has no spaces, see <bugzilla>60816</bugzilla>.
+This is due to an identified Java Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8172336">UI stuck when calling JEditorPane.setText() or JTextArea.setText() with long text without space</a>.
+</li>
+</ul>
+<ul>
+<li>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
+but otherwise its behaviour is not consistent (or clearly specified).</li>
+
+<li>
+The numbers that appear to the left of the green box are the number of active threads / total number of threads,
+the total number of threads only applies to a locally run test, otherwise it will show <code>0</code> (see <bugzilla>55510</bugzilla>).
+</li>
+
+<li>
+Note that under some windows systems you may have this WARNING:
+<source>
+java.util.prefs.WindowsPreferences
+WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
+x80000002. Windows RegCreateKeyEx(…) returned error code 5.
+</source>
+The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
+</li>
+
+<li>
+You may encounter the following error:
+<source>java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</source>
+ if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature
+ algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits.
+This error is related to increased security in Java 8+.
+<br></br>
+To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
+the Java <code>jdk.certpath.disabledAlgorithms</code> property. Remove the MD2 value or the constraint on size, depending on your case.
+<br></br>
+This property is in this file:
+<source>JAVA_HOME/jre/lib/security/java.security</source>
+See <bugzilla>56357</bugzilla> for details.
+</li>
+
+<li>
+Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers.
+This is due to a known Java bug, see Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8065373" >JDK-8065373</a>
+The fix is to use JDK8_u45 or later.
+</li>
+
+<li>
+View Results Tree may fail to display some HTML code under HTML renderer, see <bugzilla>54586</bugzilla>.
+This is due to a known Java bug which fails to parse "<code>px</code>" units in row/col attributes.
+See Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8031109" >JDK-8031109</a>
+The fix is to use JDK9 b65 or later (but be aware that Java 9 is not certified yet for JMeter).
+</li>
+
+<li>
+JTable selection with keyboard (<keycombo><keysym>SHIFT</keysym><keysym>up/down</keysym></keycombo>) is totally unusable with JAVA 7 on Mac OSX.
+This is due to a known Java bug <a href="https://bugs.openjdk.java.net/browse/JDK-8025126" >JDK-8025126</a>
+The fix is to use JDK 8 b132 or later.
+</li>
