[hibernate-dev] IntelliJ 16 and Java 8 for tests

We have been having an ongoing discussion about using Java 8 features in tests. My only argument against that was the fact that doing so makes it impossible to run tests in IDE (IntelliJ at least) unless I set the "language level" for the whole module to Java 8 which means I possibly miss using Java 8 calls in src/main. Well IntelliJ 16 is in EAP and I have been using it for almost a week now. One of its major changes is a move to a more Gradle-like view of a module on importing a Gradle project. So when I import ORM, hibernate-core e.g. is split up into 2 IntelliJ modules... or more correctly one per SourceSet. Now I can set the "language level" independently of main versus test. So once IntelliJ 16 becomes more stable, I think we can consider allowing Java 8 features in tests if anyone still wants to.
