On the MacOS X version of Netbeans, clicked Services->Servers->Resources to expand the tree, the NPE appears on that action

Tried 6.5 beta for the first time.    

1)  Started it.  
2)  Went to the Services explorer
3)  Expanded the "Servers" node, with the intent of starting my glassfish instance.

When the node expanded, this exception was thrown.
