[hibernate-dev] Analysis of hibernate-release-4.3.6 dependency on JDK-Internal APIs

[Steve Ebersole]

Correct.  Starting in 5.0 we are using a combo of jaxb + stax for XML
parsing, instead of dom4j.  At the moment we have no concrete plans to do
any 4.x release with that approach, although it is one of the items we want
to discuss when we get together in a few weeks: specifically a possible
4.4/4.5 release with a *limited* subset of concepts/code ported from 5.0
back to the 4.x codebase.
