The ControllerMode approach sounds better. I expect starting a thread in create() won't help much in many cases, as the main thread will quickly proceed to start and then block. Unfortunately, JBM opens 2 of the 3 underlying JChannels in AS 5, and it's deploying as an mbean. HAPartition is opening the 3rd channel and definitely can benefit from this. The other services (JBC) are opening MuxChannels, which really just multiplex on the underlying JChannel and thus don't block. But, we want to move to using the JGroups shared transport, in which case each service will have its own JChannel; I need to think through how to use the ControllerMode to improve the startup speed.
