Its perfectly legal in JMS to do this - many people do - so we
shouldn't create a warning for perfectly valid JMS applications.

Oh, you mean consumer.receive()?

Its starts to get a little complex now; as the thread doing the
consumer.receive() could be different to the thread doing the
connection.start(), so its still valid to do a consumer.receive()
before the connection is started.

Plus lots of people use the async consumption model - which this
approach won't help; so I think i'd rather a more general catch all
that consumers created on a connection that doesn't get started within
some time window (1-5 seconds or so) we generate a warning.
