I just tested this on the main branch with an OpenWire JMS producer and the STOMP client in our test-suite. The OpenWire JMS producer did not invoke setJMSPriority and the STOMP client received a message with a header "priority" with the value "4".
What version of ActiveMQ Artemis are you using? Can you provide steps to reproduce what you're seeing or possibly a STOMP protocol trace log [1] from when you observe this behavior?
