ThreadPoolExecutor.AbortPolicy

AI-generated Key Takeaways

ThreadPoolExecutor.AbortPolicy is a handler for rejected tasks that throws a RejectedExecutionException.
It implements the RejectedExecutionHandler interface.
Upon task rejection, the rejectedExecution method is invoked, which immediately throws a RejectedExecutionException.
This policy provides a straightforward approach by halting execution and notifying the caller about the rejection through the exception.
