I’ve verified it is indeed a CoreMessage

The bytes should be the same as far as I can tell.

But our clients are JMS and our client code makes JMS calls: BytesMessage m = session.createBytesMessage(); m.writeBytes(bytes); When those packets are handled by our server plugin, and I do public void beforeSend(ServerSession session, Transaction tx, Message message, boolean direct, boolean noAutoCreateQueue) { var cm = (CoreMessage)message; var bytes = cm.getDataBuffer().byteBuf().array(); First, is it correct to downcast to CoreMessage? Second, will the bytes be identical to the bytes I put into the JMS message, or will Artemis add some “framing” around it?
