Code Review
This pull request introduces a custom termination condition AfterNumberOfNewOutputs in FileIOTest.java to improve the reliability of testMatchWatchForNewFiles by stopping polling after a specific number of outputs or a 10-second timeout. The feedback points out that using numFiles for the single-file update matcher is conceptually incorrect and fragile, and suggests using a literal value instead.
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.

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 addresses intermittent failures in the 'FileIOTest' suite by improving the reliability of file watching tests. By replacing purely time-based termination conditions with a hybrid approach that includes a count-based condition, the tests are now less susceptible to environmental latency during CI execution.

Code Review
This pull request introduces a custom termination condition AfterNumberOfNewOutputs in FileIOTest.java to stop polling after a specific number of new outputs, and updates testMatchWatchForNewFiles to use this condition in combination with a larger timeout. The review feedback suggests defensively handling potential NullPointerException issues caused by auto-unboxing of the nullable Integer state parameter in the onSeenNewOutput and canStopPolling methods.
