Michael Chen updated AMQ-2929:
------------------------------
Attachment: ActiveMQConsumerTest.java
ActiveMQConsumerTest.xml
Attached the test source program and its Spring xml. A producer is needed that
uses the same jmsFactory defined in this XML to pump some messages (compressed)
to the "test.registration" queue before running the test program. No message
will be retrieved due to the ZipException.
> Compressed text message received by consumer uncompressed

> Key: AMQ-2929
> URL: https://issues.apache.org/activemq/browse/AMQ-2929
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.3.2
> Environment: ActiveMQ 5.3.2 / Camel 2.2.0
> Reporter: Michael Chen
> Attachments: ActiveMQConsumerTest.java, ActiveMQConsumerTest.xml
>
>
> I have a queue setup to send and consume compressed text messages. This is
> done via Spring setting ActiveMQConnectionFactory.useCompression to true. If
> the consumer connects to this queue before the first message is arrives,
> everything works great.
> If the messages are sent to this queue before the consumer connects, those
> early messages will cause ZipException "unknown compression method" when
> consumed by the belated consumer. Debugger shows that the
> ActiveMQTextMessage.content already contains the uncompressed text (with 4
> leading length bytes) when ActiveMQTextMessage.getText() is called.
> If I set useCompression to false, early messages are consumed with no
> problems. Please look into this.
> I notice that after ActiveMQTextMessage.getText() decompress the message, it
> does not set compressed to false. Not sure if that is the cause.
