I was checking to what was causing an OME on my box, and I figured out the problem was on Management registering few objects on JMX making few objects reachable and holding several MessageReferenceImpl on the memory. I'm changing RandomFailoverTest and MultiThreadRandomFailoverTest to disable JMX on Management. That shouldn't be a problem but I wanted to communicate why I'm doing that here.
