## Summary of Changes Hello @stankiewicz, I'm Gemini Code Assist[^1]! 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 a critical concurrency issue within the `ParDoLifecycleTest` by upgrading the `callStateMap` from a standard `HashMap` to a `ConcurrentHashMap`. This change ensures that the test's internal state tracking mechanism can handle multi-threaded access without introducing race conditions, thereby improving the reliability and accuracy of the test in concurrent environments. The modifications also include adjustments to the test setup and validation logic to align with the new thread-safe map implementation. ### Highlights * **Concurrency Bug Fix**: Resolved a concurrency bug in `ParDoLifecycleTest` where `callStateMap` was accessed by multiple threads without proper synchronization, leading to potential race conditions. * **Thread-Safe Map Implementation**: Replaced the non-thread-safe `HashMap` with `ConcurrentHashMap` for `ExceptionThrowingFn.callStateMap` to ensure thread-safe operations. * **Test Setup Refinement**: Modified the `setup()` method to clear the `callStateMap` instead of re-initializing it, which is appropriate for a static `ConcurrentHashMap`. * **Correct Map Cloning for Validation**: Updated the `validate` method to correctly create a synchronized map from the `ConcurrentHashMap`'s entry set for assertion purposes, replacing the direct `clone()` call which is not available on `ConcurrentHashMap`. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
