Description

Following QPIDJMS-600, when local resource teardown (e.g due to a connection.close()) overlaps with similar teardown provoked by remote connection closure, the session shutdown attempts to await async send completions can NPE, causing it not to shut down the related completions executor, if it tries to use the underlying provider after it has gone.
