[infinispan-dev] Infinispan Test language level to Java 8?

Galder, we may be doing such a thing :) The test suite is meant to 
verify correctness of our libraries when executed against a concrete set 
of external dependencies, with clearly specified supported versions or 
version intervals - the jdk being the most important of them.

Since we'll no longer be able to run on jdk 7 we can no longer support 
jdk. Even if animal-sniffer cheerfully reports we've not broken binary 
compat, that still does not mean much when it comes to jdk version 
specific issues, or jdk maker specific issue (remember the IBM jdk 
oddities).

Mavenwise, I think it is not possible to have a different compiler 
language level for module sources vs. test sources and Eclipse and 
Intellij also cannot cope with two source levels per module, so this 
would introduce some unnecessary development discomfort.  I would vote 
no for this.
