What does this type of thread do and could you give me any pointers on where to look.
Those are not thread types, they are merely the name of the threads. And a Java program can name a thread anything that it wants to, so all you can do is speculate on what the threads does by its given name -- meaning it is related to RMI communications.
CPU resource is being consumed over time in App 4.3 even when program test is idle.
It is difficult to guess what the thread is doing unless we can see the code. My guess is the rmi thread is doing some thing in a periodic way. Do you see the CPU resource goes up and down or what pattern do you see??
