Re: [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>.
