Hey,
few considerations / suggestions:
1) StringBuffer does not override hashCode, use String.hashCode; look here
for an example on how to implement correctly a PK's hashCode and equals:
http://www.ejbnow.com/ejbtips/ejbtip_1.html.
2) a instanceof A returns false if a == null; casts have a runtime overhead,
so the less you cast the better.
3) JBoss is smart enough to behave correctly even if PKs are not implemented
correctly, so your problem is elsewhere.
4) Unfortunately, you did not posted OS, JDK, JBoss' version, CMP or BMP,
server and client stack traces, nor the client code that receive the
exception... Post more info, and I'll try to help you if I can.
Regards,
Simon
