Speaking of WTP... it appears that the *org.eclipse.persistence.jpa*
feature no longer exists. The *org.eclipse.persistence.jpa* PLUGIN is
still part of WTP (and therefore Kepler), but it's now only wrapped by
the org.eclipse.jpt.jpa.feature. If you currently depend on the old
org.eclipse.persistence.jpa feature, you should now depend on either
just the plugin(s) you actually need, or the new feature.
I couldn't find references to this feature in hibernate tools so it should be fine (at
least for hibernate tools).
Also couldn't spot this change at
