Integrating the GroupManager into the PIM
Making the GroupManager work with PIM should have been a simple task, but we encountered some difficulties which have slowed down our work. In particular we have discovered that the DatagramSocket were not implemented in the JikesRVM. Besides, classpath's version is blocking and we couldn't directly make us of it. What we have done consisted in taking the DatagramSocket code from classpath, modifying it in order to make it non blocking and updating our Mobile Jikes RVM in order to run properly the new code.
Now we can make use of datagram sockets and the GroupManager is fully integrated in the PIM.
