-----------------------------------

             Summary: EJB client: NPE is returned to the client in case of server crash
                 Key: AS7-3826
                 URL: https://issues.jboss.org/browse/AS7-3826
             Project: Application Server 7
          Issue Type: Bug
          Components: Clustering, EJB
    Affects Versions: 7.1.0.Final
            Reporter: Radoslav Husar
            Assignee: jaikiran pai
            Priority: Critical
             Fix For: 7.1.1.Final


In case of remote server crashing, the client gets NPE.

# NPE is not telling at all, I m sure that the client knows what went wrong and can throw a more meaningful exception.
# AFAIR in EAP5 the client could do a retry and not fail. I guess this is still part of discussion whether this will be supported.
