Description

Consider the following cache configuration:

• Atomicity mode: Transactional
• Cache mode: Partitioned
• Backups: 1

If a continuous query is registered for such cache, then it's not processed on backup copies. It results in remote filters not being called on backups and lost events on changing topology.

Test case is attached: CacheContinuousQueryTxBackupTest.java
