[hibernate-dev] JDK 11 Early Access build 12 available

Wed May 9 17:30:38 EDT 2018

Hi Dalibor!

specifically about the version parsing we have hit some in Apache Karaf:
 - https://issues.apache.org/jira/browse/KARAF-5725
I previously reported the same for JDK10:
 - https://issues.apache.org/jira/browse/KARAF-5641

(the JDK10 related issue was resolved but it needs further changes to
deal with JDK11)

Even solving those it's a problem for OSGi testing as e.g. Pax Exam,
the integration testing tool we use to test with Karaf, was not
updated to match the latest Karaf issues. So to summarize currently
I'm not sure how to test anything on OSGi, we probably should look at
alternative integration testing tools.

Gradle is affected by the "version parsing" issue as well; it's fixed
now but wasn't released yet:
 - https://github.com/gradle/gradle/issues/4515

I've tested the nightly builds and it's ok, however even the nightly
builds only aim at JDK10 compatibility; JDK11 is scheduled for future
work.
We used the nightlies to test on both JDK10 and JDK11 and it seems to
work quite well, yet I have several other failures which I believe are
not related to Gradle nor specifically to the version format, so it's
all a bit premature to evaluate.
We will of course report issues to Gradle and/or others when things get clearer.

Next, coming from our Maven projects we have Surefire also chocking on
the version:
 - https://issues.apache.org/jira/browse/SUREFIRE-1439

this one was worrying me most as it took a long time to be fixed; as
you can see I reported it back in November 2017, during our JDK10
early access testing period.

Ironically some of those issues won't be triggered by the JDK11 final
release as the "-ea" part is the problem trigger, so maybe it will be
fine but it's having me disable large portions of our testsuites.

I guess the fact that JDK10 is no longer flagged as "ea" is what is
causing most of these issues to get reported in pairs: some libraries
fixed without the postfix first and then need a second patch when
people start looking at -ea versions; may I suggest to not change it
further for the LTS, or maybe even consider an enhancement: provide an
alternative to "-version" meant to facilitate machine parsing. Having
a prefix of two "--" while at it :)

I'll spare you details of the issues not related to versions at this
stage, we still have much work to do.

Thanks and regards,
Sanne
