279-286: Consider broader implications of thread pool executor type checkingWhile the changes to
startCustomThreadPoolMonitormethod improve compatibility with different thread implementations, it's worth considering the broader implications:
- Are there other places in the codebase that might benefit from similar type checking?
- Should we update the documentation or JavaDocs to reflect that custom thread pools may use executors other than
ThreadPoolExecutor?- Is there a need for a more generic monitoring solution that can handle different types of executors?
Consider reviewing the entire codebase for similar patterns and potentially create a more generic solution for thread pool monitoring that can accommodate different executor types.

🛠️ Refactor suggestion
Improve type checking and error handling for custom thread pool executors
The addition of the type check for ThreadPoolExecutor is a good improvement for compatibility with different thread implementations, including virtual threads. However, there are a few suggestions to enhance this change:
- The indentation of the new code is inconsistent with the rest of the method. Please align it properly.
- Consider using a more descriptive variable name instead of
tmp, such asexecutor. - Add error handling or logging for cases where the executor is not a
ThreadPoolExecutor.
Here's a suggested refactoring:
-
- Executor tmp = pool.getUserExecutor();
- if (tmp instanceof ThreadPoolExecutor) {
- customThreadPoolMonitor.setThreadPoolExecutor((ThreadPoolExecutor) pool
- .getUserExecutor());
- customThreadPoolMonitor.start();
- poolNames.add(pool.getThreadPoolName());
- }
+ Executor executor = pool.getUserExecutor();
+ if (executor instanceof ThreadPoolExecutor) {
+ customThreadPoolMonitor.setThreadPoolExecutor((ThreadPoolExecutor) executor);
+ customThreadPoolMonitor.start();
+ poolNames.add(pool.getThreadPoolName());
+ } else {
+ LOGGER.warn("Custom thread pool '{}' does not use ThreadPoolExecutor. Monitoring will be skipped.", pool.getThreadPoolName());
+ }This refactoring improves code readability, maintains consistent indentation, and adds logging for cases where the executor is not a ThreadPoolExecutor.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary by CodeRabbit
ThreadPoolExecutorinstances are set in the custom thread pool monitor, reducing the risk of runtime errors.
