Steve Loughran commented on SLIDER-790:
---------------------------------------
going to change this to update
{{<project.java.src.version>1.6</project.java.src.version>}} instead; that
propagates to the enforced java version property too. And then add some Java7+
code in a test to verify the option works
> Enforce JDK7 javac for builds
