Support ACKNOWLEDGEMENT_MODE for JmsIO#39253
Conversation
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request adds support for configurable acknowledgement modes in JmsIO, enabling better compatibility with various JMS providers and performance tuning. The changes involve a significant refactoring of how JmsIO manages JMS sessions and consumers, ensuring that resources are correctly handled across different acknowledgement strategies. Additionally, the PR improves the reliability of integration tests and addresses a bug in the direct runner's checkpoint finalization logic. Highlights

Code Review
This pull request introduces support for multiple acknowledgment modes in JmsIO (CLIENT_ACKNOWLEDGE, CLIENT_ACKNOWLEDGE_UNSAFE, and INDIVIDUAL_ACKNOWLEDGE) to optimize message consumption and prevent message backlogs, along with corresponding updates to checkpointing and reader closing logic. The review feedback highlights two important issues: a potential race condition in JmsIO.java where the consumer and session could be closed concurrently on different threads in CLIENT_ACKNOWLEDGE mode, and a potential hang during reader shutdown if a RuntimeException in JmsCheckpointMark.finalizeCheckpoint() prevents the decrement of activeCheckpoints.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

* CheckpointMark behavior in alignment with different ACKNOWLEDGEMENT_MODE * Ref count active checkpoint for quicker onClose that releases session * Fix hanging checkpoint when no incoming data in direct runner. This allows us to do an exact assert * Optimize long running unit test usign a short retry * Re-enable AMQP integration test after stuck unack messages resolved
Introduce INDIVIDUAL_ACKNOWLEDGEMENT for supported providers
(Re)introduce CLIENT_ACKNOWLEDGEMENT_UNSAFE that restore the behavior prior to Beam 2.55.0, provide a way to mitigate #30218 (comment)
