I just ran into this issue as well. Had never seen it before in either
3.0 or 3.0.1RC1. My setup does not involve EAR files (yet), simply a jar
with all the entities, a jar with all the session beans, and a war file
with some cactus tests inside it. The place where it stopped seems
arbitrary. I undeployed all the jars and the war, rebuilt them,
redeployed them and I have managed to avoid the problem so far.
Heres' my stack trace:
