Currently the main rollup integration test disables all thread leak detection:

I think that this should be unnecessary, I think that the only thread that should be filtered out here is the ObjectCleanerThread from Netty (relates #31232). It looks like this was added for the trigger_engine_scheduler thread. Can we look into this and see if the thread leak none can be removed and reduced to filter the ObjectCleanerThread only (extend XPackIntegTestCase)?
