I notice the NPE still exists in JBoss Messaging as well.
I believe the NPE solved you're mentioning is another NPE, in another case.
I am currently dealing with this exception in our testsuite, as we are
updating JGroups at our development branch. (STABLE)
There is some race condition between channel.connect() and when the View
is sent. With JGroups 2.4, and the stack we are using at JBM, the view
would aways be sent while channel.connect() is called (synchronized). It
looks like this has changed on 2.6. (Probably another thread sending the
view... or the Stack is different).
On my tests I assumed this was because we didn't have the flush
protocol, but i can see that Flush is being used at the Multiplexor
channels.
I am doing some debug right now, and I will update it as soon as we have
solved this.
