Issues with topic usage have been experienced on older releases, and whilst these appear to be rectified in the current codebase there are some testing gaps that should be addressed to guard against reoccurence:
1.Test durable topic subscriptions where the client disconnect with and without unack'd messages in subscription queue.
2.Test ttl on messages published to topics where selectors are used such that not all message in subscribers queue are ack'd works
3. Add volume test as follows:
- 1 publisher
- 50 consumers using selectors
- Publish 50000 1k transient messages, leaving 10% not matching selectors - check that these messages are not retained
