DO NOT REPLY [Bug 51268] New: HTTPS request through an invalid proxy causes NullPointerException and does not show in result tree

https://issues.apache.org/bugzilla/show_bug.cgi?id=51268

             Bug #: 51268
           Summary: HTTPS request through an invalid proxy causes
                    NullPointerException and does not show in result tree
           Product: JMeter
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: HTTP
        AssignedTo: notifications@jakarta.apache.org
        ReportedBy: w.a.hajenius@gmail.com
    Classification: Unclassified


Created attachment 27070

Test script (.jmx) and log files

When performing a HTTPS request through a non-existing proxy server (i.e. there
is a value specified, but it's not an actual valid proxy server), JMeter
internally gives a NullPointerException and *does not show the (failed) sampler
result* in the listeners. As a consequence, the user has no idea that anything
went seriously wrong, unless the missing result is noticed.

This can easily be reproduced, please see attached files:
"HTTPS_request.jmx" does a simple HTTPS request and displays the result.

(1) Start JMeter with VALID --proxyHost and --proxyPort parameters
(2) Run the test
(3) You get a green result in the table. This corresponds to attached log
"jmeter_with_good_proxy.log"

(4) Start JMeter with INVALID --proxyHost and --proxyPort parameters
(5) Run the test
(6) You get NO result in the table. This corresponds to attached log
"jmeter_with_bad_proxy.log" 

I'm using version 2.4 r961953. As you can see from the log, for an invalid
proxy it gives a NullPointerException that bubbles up.

Even though the NPE should not happen, it's easy enough to allow for it by
catching Exception rather than just the expected failures.

Log:
Bug 51268 - HTTPS request through an invalid proxy causes NullPointerException
and does not show in result tree.
Rather than delegating to the JMeter thread handler for "unexpected" failures,
ensure all Exceptions generate a sample error.

This looks to be a bug in Java; it should not generate an NPE.
If there is a problem with the proxy, it should report an IOError, which would
be handled as a sampler error.

You appear to be using Java version 1.5.0_12 which is quite old.
Does the problem still occur with the latest Java version?
