[hibernate-dev] Trying Hibernate 5.0.0.Beta1

Actually this may have been a brain-fart on my part when building the
release.  I think I may have forgotten to pass in the Java 6 JDK to the
build, which I use to set the javac bootclasspath.  So in that case it
would have used the bootclasspath from the Java 8 JDK I used to launch
gradle.

If you get a chance, you can test that theory by getting the sources and
running the hibernate-core build again.  You'd have to use Java 8 to launch
Gradle and pass -PJDK6_HOME=<path-to-java7-jdk>.
