That interceptor or anything like it would be a great idea. Much as I love
to wrap my code with
try {} catch printStackTrace,
it would be nice if the container provided some way to see those little
nasties all us application developers put in from time to time.

Subject: Re: [jBoss-User] Enity beans works in PR3 but fails in PR4!
Generally the "null" on the console output indicates a
NullPointerException of some sort - and this is supported by the first
line in your stack trace below.. There may be a NullPointerException in
your bean. Can you put try/catches in the ejbPostCreate and whatever else
might get called after that and see? If it's not in your bean, it will of
course be more painful to track down.
Developers: Perhaps we could create an "ExceptionInterceptor" that
would print a stack trace of any exception that occurs during a call? For
use in debugging only, of course...
