Hi devs,

I’d like to propose that we move to Java 8 as the minimal Java version supported for XWiki 8.0+.

The rationale is:

* Java 7 is end of life since April 2015. * It brings [Default Methods| https://docs.oracle.com/javase/tutorial/java/IandI/defaultmethods.html] which would make retro compatibility a lot easier for us (it's very hard to add new features to existing API right now). * Required for: ** Infinispan 8 ** JGroups 4 ** Jetty 9.3+ seems to require Java 8 (or maybe it's just optimized for it, http://download.eclipse.org/jetty/ is not crystal clear about what "Java 8+" means exactly)

Nice to have * Lambda Expressions * Repeating Annotations which would probably allow us to use several times \@Named instead of \@Component(hints=\{"hint1", "hint2"\}) for example * New date/time APIs (pretty much what is in Joda Time). We should refactor our $datetool velocity tool to make the java.time api available from velocity * more…

See http://jira.xwiki.org/browse/XCOMMONS-878

Here’s my +1 and my +1 to start requiring Java 8 for 8.0M2.

Thanks -Vincent

Vincent, can you state which minimum MacOSX, Ubuntu, and Windows version this means? I know 10.6 is out and I've been challenged for this since XWiki moved to Java7 already but that's past (my solution was, then, to not upgrade my wiki). It'd be interesting to know the coming limitations. paul

Just found this: http://java.com/en/download/help/sysreq.xml

This is for Oracle’s JVM but all you need is to find a Java 8 JVM that works for your OS. I don’t know the requirements for OpenJDK or other JVMs. Thanks -Vincent

Ok more than 72 hours have passed, here are the results: - 6 binding +1 - 2 non-binding +1 - no 0 and no -1 The VOTE is passed. We now need to make CLIRR work with Java8 before we can move the build to require Java 8.
