It works OK for the thread pools used by TP but a couple of
problems:
Problem 1: I need to kludge it a bit: it turns out that I need to do a
channel.connect() before I can modify/set the TP thread pools because
the thread pools are created in TP.start(). This means that non-daemon
threads can get created before I have a chance to modify the setting.
What if I check in TP.start() if thread_pool/oob_thread_pool is already set and don't
create a thread pool of already set ? Then you could create a JChannel, set the thread
pool(s) and then call JChannel.connect().
Problem 2: there are other threads at the transport level that get
created using ProtocolStack.getThreadFactory() and there is not way to
override how this thread factory gets created.
I could provide setters for the 2 thread factories in ProtocolStack and make them
non-final. Would that help ?
