We managed to reproduce our message size change problem with simple java programs (see QueueReader.java <http://activemq.2283324.n4.nabble.com/file/n4728024/QueueReader.java> and QueueWriter.java <http://activemq.2283324.n4.nabble.com/file/n4728024/QueueWriter.java> ) based on your QueueExample.
One of them sends a binary message (array of bytes), another one reads this message. The pom.xml files were changed so that the Artemis server is not started. We ran a standalone Artemis 2.1 server. The test programs were built with different Artemis versions, 1.5.5 and 2.1. When the sender is 1.5.5 and the receiver is 2.1, the message read back is always 4 bytes longer, garbage bytes are added to it. When the sender is 2.1 and the receiver is 1.5.5, the message read back is always 4 bytes shorter, the last 4 bytes are lost. When both programs are built with the same version of Artemis, does not matter which, the read back message is correct. Besides, if we send a text message, it is read back correctly. -- View this message in context: http://activemq.2283324.n4.nabble.com/Artemis-2-1-0-compatibility-with-1-5-x-tp4727741p4728024.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
