[hibernate-dev] Java 9: progress on compatibility

[Sanne Grinovero]

Hi all,
please try to have a look at this page when you have a moment:
 - http://ci.hibernate.org/view/JDK9/

Hibernate Search is working, and it shouldn't be too hard to get the
others "green" as well.

I've disabled some integration tests to get there, notably:
 - OSGi tests: Karaf is not ready for it.
 - Documentation build: Asciidoc will probably need an update.
 - WildFly integration tests: the WildFly team is aware, will need a
minor upgrade.

I don't believe these issues are relevant, so I'm satisfied that all
other tests working fine mean that the project will pretty much work
out of the box for end users - at worst their container won't work,
but that's not our responsibility to test for.

Could you all contribute a bit to get all projects show "green" on this page?

Some "workarounds" you might want to apply:
 - the Logger interfaces won't compile because of a known issue, this
can be worked around for now by having the compilation phase also
explicitly depend on this artifact:
https://github.com/hibernate/hibernate-search/blob/master/pom.xml#L878-L883
 - you'll have a ClassNotFoundException on JAXB usage unless you set
this JVM flag: https://github.com/hibernate/hibernate-search/blob/master/pom.xml#L1429
(This one is not a bug but will be required to be set by end users as
well - or we provide our own XML parser, that might be more user
friendly).

As far as I know, other issues with the build tools have been solved
already - including Gradle.

Thanks,
Sanne
