I have a test which sends a message to a queue named "spaceattheend " with qpid-jms and then tries to receive the message with activemq-client. The message is not received.

I investigated, and it seems that activemq-client strips the trailing space and attempts to receive from queue "spaceattheend" (without the space). This fails.

This shows that it is possible to have queues on the Artemis broker that cannot be accessed by activemq-client.
