If a device properly sends a Bye-message on shutdown, remaining data is not cleaned up properly in the client. The leads to ClassCastExceptions in the DefaultReportProvider (trying to cast from the different ContextState-types (DefaultBICEPSLocationContext a.s.o.) to an MDIBObjectLifeCycleListener).

If the Exception is thrown, the entire BICPESClient seems to block or fail, requiring a restart of the java application..

    This is just one device (hmi) that also uses the client api started and closed. Search for devices may be triggered periodically (20sec interval).
