Suggest you work on a unit test that can reproduce otherwise we will just keep
stabbing in the dark.

That results in a different NPE at:

One case that looks like a possibility is in the collectBrokerInfos method:
{code}
try {
remoteBrokerInfo = futureRemoteBrokerInfo.get();
if (remoteBrokerInfo == null) {
fireBridgeFailed();
}
} catch (Exception e) {
serviceRemoteException(e);
return;
}
{code}
we should probably be returning after the call to fireBridgeFailed otherwise
the method would continue on with the remoteBrokerInfo being null which could
lead to this error. The futureRemoteBrokerInfo future is cancelled in
transport listener set in the start method.
