Contrary to what I thought by reading the manual, sessions cannot be shared among threads. One easy fix is to make the ArtemisQConnector methods synchronized as well as the sendMessage method of ArtemisQProducer---look at the stack traces in the Spring log. A more sophisticated approach would be to wrap the Artemis session I/F, have a pool of sessions and make them thread-scoped. Not sure it's worth the trouble though.

See attached Spring log file.
