Subject [jira] Commented: (AMQ-1095) Invalid messages selected from durable topic

Rainer Klute commented on AMQ-1095:
-----------------------------------

It seems to me that the bug is in the Kaha persistence manager namely in the method org.apache.activemq.store.kahadaptor.KahaTopicMessageStore.addMessage(ConnectionContext
context, Message message). Here the message is added to the message containers of *all* topic
subcribers without checking their respective selectors. Am I on the right track here or not?

> We think we've found an issue with durable topic subscriptions and message selectors.
> The attached application sends messages with an int property i with values 0..19 to a
topic. We also have a durable subscription to the topic, selecting messages for which i%2=0.
After sending the messages, the connection is started, allowing the consumer to receive the
messages we've published that match the selection criterion. The second and every subsequent
time we run the application, we see the following:
> message.i = 19
> message.i = 0
> message.i = 2
> message.i = 4
> message.i = 6
> message.i = 8
> message.i = 10
> message.i = 12
> message.i = 14
> message.i = 16
> message.i = 18
> message.i = 19 does not match the message selector criterion but it reaches our message
handler anyway.
> Tested with ActiveMQ from trunk, revision 486090.
