[jira] [Created] (AMQ-3889) Body Preview of BytesMessages change
when browsed multiple times from QueueViewMbean
Robin Kåveland Hansen created AMQ-3889:
------------------------------------------
Summary: Body Preview of BytesMessages change when browsed multiple times from QueueViewMbean
Key: AMQ-3889
URL: https://issues.apache.org/jira/browse/AMQ-3889
Project: ActiveMQ
Issue Type: Bug
Components: JMX
Affects Versions: 5.5.1
Environment: Linux 64-bit, multiple java versions.
Reporter: Robin Kåveland Hansen
Priority: Minor
When using the browse method of org.apache.activemq.broker.jmx.QueueViewMBean to obtain CompositeData of messages, the Body Preview of BytesMessages changes between each browse.
I am not sure if that is intended behaviour, but I have written a testcase that illustrates it.
I have also narrowed it down to org.apache.activemq.broker.jmx.OpenTypeSupport.BytesMessageOpenTypeFactory, which uses ActiveMQBytesMessage.readBytes but does not call reset afterwards.

--------------------------------
Thanks for your quick response. My aim to create a external tool using JMX that will monitor few ActiveMQ Queues periodically and peek(browse) into certain non-well formed messages and raise alerts.
Few questions, if you can answer, will help me a lot.
1) Is there a workaround available for this?
2) Is this an issue with activeMQ JMX agent service? The upcoming patch to be applied to activeMQ service?
3) I guess even though the browse shows message with null characters(after couple of browsing on the same message), read message actually fetches the message properly, please confirm if this is correct.
Thanks
Sathish

ActiveMQ 5.7.0 is undergoing the release process now. You can wait a few days for that or grab one of the nightly SNAPSHOT builds.
