[hibernate-dev] ORM 5.1 vs compatibility with Java 6

Hi Sanne,

I didn't notice the failures either. I've been running it with JAVA6_HOME
pointing to jdk7, but I can't remember why I would have changed it to that.

It sounds like 5.1 branch will be a product branch for a while, so if it's
easy to make it compatible to JDK6, then I'd prefer to do that.

It looks like there are only 2 failures:
1) an unused import for import java.util.Objects, which is easily deleted.
2) ReflectHelper#JAVA_CONSTANT_PATTERN uses java.util.regex.

Vlad, is there some other flag that can be used that is compatible with
JDK6? If not, is there some other reasonable flag that we can use instead?
