[hibernate-dev] Trying Hibernate 5.0.0.Beta1

Tue Mar 31 19:30:38 EDT 2015

Nope.  It just effects any code compiled with Java 8 even though the change
is internal.  The problem is the generated bytecode incorporates this
change.   Like I said, this should be compiled with 1.6 compatibility, but
that is apparently not working atm.  I am having a struggle getting a mixed
JDK build working "just right".
