Error description

  • When you use the XIO transport, sometimes exceptions occur on
    the WebSphere eXtreme Scale container server that are not
    signaled correctly to clients. If exceptions are generated on
    the container server that represents classes not present in
    the eXtreme Scale client, then the client gets a
    ClassNotFoundException exception during its attempt to signal
    the original exception to the API caller, which obfuscates the
    cause of the original exception.
    
    This APAR ensures that the ClassNotFoundException does not
    obfuscate the original exception and the client receives
    correct exception information in the form of an
    UnkownException with the correct message text.
