Thanks, Alexey.  The way it's working now is a bug: 
http://jira.jboss.com/jira/browse/EJBTHREE-946

Likely solution is to prefix the ejb name with something built up a la 
EjbContainer.getDeployment().getScopedKernelName(), i.e.

[ear=xyz.ear,]jar=abc.jar,bean=StatefulBean

That should be unique, as that's the same as what creates the 
container's unique OID.

The [ear=xyz.ear,]jar=abc.jar bit would serve well as a region prefix 
for the entity cache.
