I just added, because I needed them, two new bindings for java apis:

Connection.getCpuStats(int, long)

and

Domain.getCpuStats(int, long)

these two functions act like python's counterpart. 

I give you the .jar with sources so that, after you review it (it works but I am not entirely sure it is bug free), you could publish it thus helping java programmers who needed a cpu indicator too.
