diet ice commented on EJBTHREE-698:
-----------------------------------

This has been the bane of remote unit testing of session beans for me, and predates java 1.6.  The cause has generally been references to classes in the session bean that are not in the client classpath, but I've never been able to determine which classes are missing when I get this exception.
