Since JMS allocates some resources on behalf of a
IMessageProducer outside the .NET CLR, clients should Close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.
There is no need to close a message producer if the producer's parent session or connection is closed, or if its parent context has been closed with CloseAll.
|MessageException||if JMS fails to Close the producer due to some internal error.|
