TaskEventListener is not working as expected with "Per-Process-Instance and per-request" runtime strategies

Issue

• We have created custom task event listener to BPMS. But it is deployed in production setup, it is firing only afterTaskAddedEvent but not any of the task update events like afterTaskActivatedEvent/afterTaskClaimedEvent/afterTaskStartedEvent etc if we use Per-Process-Instance/per-request runtime strategies while deploying kjar. Is there any configuration setting we need to verify?.
