  Caused by: java.rmi.ServerException: The server process [xxxxxxx], that the client was connected with, is not working. Check its traces for details. Since the remote object is not Redirectable, client-server communication will not work. Check the logs on the client side containing this exception in order to identify the responsible application/component, which shall lookup the remote object again in order to make it operational.
