Log Message:	Added parent filter passing, so the packet can be passed on. Also had to make a quick fix because a null pointer exception was being thrown on the substring() part. I think this was because when a message came in over CORBA rather than UDP it didn't have the 0 (byte 0 that is) at the end.
