 * @throws com.arjuna.wsc.InvalidStateException

/*
	 * TODO
	 *
	 * See comment at head of class definition. We shouldn't have to rely on
	 * thread-to-activity association to register a participant. We currently do
	 * because the code is based on old WS-CAF models that are no longer
	 * applicable. This needs updating!
