An issue was found in the Artemis and HornetQ .When 3rd party tool send multicast messages to Artemis/HornetQ which is configured with UDP Disovery and JGroups Discovery, Artemis/HornetQ creates a huge byte array at receiving the unexpected multicast message. So, it results in heap memory exhaustion, full GC and OutOfMemoryError in the worst case.
