---------------------------------------
Seems that this bug is also in another place in EJB-3.0RC8 (sorry can't test this on
later versions) when an EJBException caused by a NPE is propagated back through another
EJB call as a EJBTransactionRolledbackException:

EJBException should set cause
-----------------------------
Key: EJBTHREE-337
URL: http://jira.jboss.com/jira/browse/EJBTHREE-337
Project: EJB 3.0
Issue Type: Bug
Affects Versions: EJB 3.0 RC3
Environment: AS-4.0.3SP1, EJB-3.0RC3
Reporter: Ortwin Glück
Assigned To: William DeCoste
Priority: Trivial
Fix For: EJB 3.0 RC4 - PFD
When a NullPointerException is thrown in a session bean method the EJBException only
provides the wrapped exception via getCausedByException() and not via the
Throwable#getCause() method. That causes stack traces to abort at the EJBException and the
real exception is lost. It makes debugging harder.
Caused by: javax.ejb.EJBException: null; CausedByException is:
null

Painful Workaround:
try {
bean.method();
} catch (EJBException e) {
if (e.getCause() == null) e.initCause(e.getCausedByException());
throw e;
}
