User reported "Only a single instance of the World Peer Group may be
instantiated at a single time" error message when restarting the NetworkManager.
Most probably caused because stopped instance is not being removed properly from
PeerGroup.globalRegistry() for some reason.
Suggestion for workaround: remove the registered after stopping and before
restarting, something like:
PeerGroup.globalRegistry.unRegisterInstance(PeerGroupID gid, PeerGroup pg);
