`Selector.poll()` will always call `pollSelectionKeys()` for channels with buffered data. `pollSelectionKeys()` will always update connection last idle time, even if the channel is muted and we don't actually read from the channel. There is an existing unit test `idleExpiryWithBufferedReceives` that fails to catch this behavior because the `MockTime` object used in the test is updated in a large enough increment to expire a connection between calls to `poll()`. After updating the test to advance time in smaller increments, the test fails without the Selector change. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
