The spec does not specify how ManagedThreadFactory instances are shut
down. I would imagine that the container would have some method in its
ManagedThreadFactory implementation class that would be called to
shutdown the ManagedThreadFactory instance. Each of those instance would
maintain a list of its threads and each of these threads would be
interrupted during shutdown.

Could you explain how this new interface method will be used during
shutdown? Thanks.

Would the intention for this be to allow creation of new threads for
various resource cleanup during component shutdown? If the
ManagedThreadFactory belongs to the same component, would this mean we
are requiring ManagedThreadFactory to be shutdown last during a
component shutdown?
