java.lang.Thread.run(Thread.java:595) In MessageSupport.getPayload(MessageSupport.java:264), if payload == null, it attempts to deserialize the byte array, which in this case is the content of the BytesMessage. StreamUtils.readObject(StreamUtils.java:159) will report "Unknown type" followed by the value of the first byte of the BytesMessage payload. (This could be misinterpreted during deserialization if the first byte happens to match a constant.) I am not sure how to recreate the test case yet (payload is perhaps typically non-null), but it happens frequently in our environment, where the BytesMessage is 95% of the traffic. This fix resolves the issue in our environment: diff -r org/jboss/jms/message/JBossBytesMessage.java 592c592 < return (byte[])getPayload(); --- > return (byte[])getBytesMessagePayload(); diff -r org/jboss/messaging/core/impl/message/MessageSupport.java 281a282,303 > public synchronized Object getBytesMessagePayload() > { > if (payload != null) > { > return payload; > } > else if (payloadAsByteArray != null) > { > payload = payloadAsByteArray; > payloadAsByteArray = null; > return payload; > } > else > { > return null; > } > } >
