Hi!

Just fyi:

Today we saw this issue again after adding

     EOModelGroup.defaultGroup().loadAllModelObjects();

to the constructor in Application.java.

This is on WO5.2.2 on solaris. The ec we use there is a child of 
session.defaultEditingContext.

The stacktrace is as follows:

java.lang.NullPointerException
