Hi,

For now, several GroupManagementService instances in the same JVM share one NetworkManager instance.

ClusterManager uses AbstractNetworkManager#getInstance(String transport) to get its NetworkManager.

However, AbstractNetworkManager always returns the same NetworkManager instance in the same JVM, because it has static field, “networkManager“.

I think it should not be static because there can be a couple of GroupManagementService instances and each of them must have its own NetworkManager instance in a JVM.

i.g.
- When there exist two GMSs which would like to join two different groups in a JVM
- When someone would like to test different transport layers(Jxta, Grizzly, etc...) in a JVM by UnitTest - this is my case. :-)

So I attached the simple diff of AbstractNetworkManager.java which does not use static field for NetworkManager.

What do you think?
