Hello Alain, Keith, I updated the Java Broker to 6.0.4 and re-run my test case 5 times. The good news is that the "AMQP header mismatch" error has disappeared. The bad news is every time I ran my test, I got the "on_transport_error: proton:io: connect: Cannot assign requested address" error.
I get the error after sending about 30 000 msgs. At each send, I am creating a new container which means new connection every time.
