Fwd: Analysis of apache-jmeter-2.11 dependency on JDK-Internal APIs
We received this message on the JMeter developer list, however the findings
apply to external projects such as yours.
So I am forwarding the details to you.
If you have any feedback, please address it directly to Oracle (addresses
in e-mail header)
Thanks!

Let me know if the report below is legible ?
JDK Internal API Usage Report for apache-jmeter-2.11
The OpenJDK Quality Outreach campaign has run a compatibility report to
identify usage of JDK-internal APIs. Usage of these JDK-internal APIs could
pose compatibility issues, as the Java team explained in 1996
<http://www.oracle.com/technetwork/java/faq-sun-packages-142232.html>. We
have created this report to help you identify which JDK-internal APIs your
project uses, what to use instead, and where those changes should go.
Making these changes will improve your compatibility, and in some cases
give better performance.
Migrating away from the JDK-internal APIs now will give your team adequate
time for testing before the release of JDK 9. If you are unable to migrate
away from an internal API, please provide us with an explanation below to
help us understand it better. As a reminder, supported APIs are determined
by the OpenJDK's Java Community Process and not by Oracle.
This report was generated by jdeps
<http://docs.oracle.com/javase/8/docs/technotes/tools/unix/jdeps.html>
through static analysis of artifacts: it does not identify any usage of
those APIs through reflection or dynamic bytecode. You may also run jdeps
on your own
<https://wiki.openjdk.java.net/display/JDK8/Java+Dependency+Analysis+Tool>
if you would prefer.
Summary of the analysis of the jar files within apache-jmeter-2.11:
- Numer of jar files depending on JDK-internal APIs: 7
- Internal APIs that have known replacements: 6
- Internal APIs that have no supported replacements: 63

Hi Philippe,
As part of the preparations for JDK 9, Oracle’s engineers have been
analyzing open source projects like yours to understand usage. One area of
concern involves identifying compatibility problems, such as reliance on
JDK-internal APIs.
Our engineers have already prepared guidance on migrating some of the more
common usage patterns of JDK-internal APIs to supported public interfaces.
The list is on the OpenJDK wiki [0], along with instructions on how to run
the jdeps analysis tool yourself .
As part of the ongoing development of JDK 9, I would like to encourage
migration from JDK-internal APIs towards the supported Java APIs. I have
prepared a report for your project release apache-jmeter-2.11 based on the
jdeps output.
The report is attached to this e-mail.
We did not get the report - the mailing list drops attachments.
If you can upload the report somewhere public and post the URL, that
would be great.
Alternatively, please create a Bugzilla issue [1] and attach the report there.
Thanks.
[1] http://jmeter.apache.org/issues.html
For anything where your migration path is unclear, I would appreciate
comments on the JDK-internal API usage patterns in the attached jdeps report
- in particular comments elaborating on the rationale for them - either to
me or on this mailing list.
Finding suitable replacements for unsupported interfaces is not always
straightforward, which is why I am reaching out to you early in the JDK 9
development cycle so you can give feedback about new APIs that may be needed
to facilitate this exercise.
Thank you in advance for any efforts and feedback helping us make JDK 9
better.
Rgds,Rory

Posted by Michael Glavassevich <mr...@ca.ibm.com>.
That's a backwards way of looking at it. Xerces and Xalan aren't using JDK
internal APIs. The JDK included these APIs from Xerces and Xalan.

Re: Fwd: Analysis of apache-jmeter-2.11 dependency on JDK-Internal APIs
Posted by Michael Glavassevich <mr...@ca.ibm.com>.
That's a backwards way of looking at it. Xerces and Xalan aren't using JDK
internal APIs. The JDK included these APIs from Xerces and Xalan.
