Regarding Java exception handling mechanisms, there's an important aspect to consider about how exceptions propagate in multithreaded environments.

Based on the original question, when an uncaught exception occurs in a thread, the thread terminates but other threads continue running. This is fundamentally different from how exceptions work in single-threaded applications where an uncaught exception terminates the entire program.

I'd like to request clarification about a specific aspect of exception handling in multithreaded contexts:

When using ExecutorService or ThreadPoolExecutor, how exactly are exceptions handled when they occur in worker threads? Are they silently swallowed, or is there a mechanism to propagate them to the main thread? The documentation mentions UncaughtExceptionHandler, but it's not clear how this integrates with thread pools.

Additionally, could someone clarify the best practices for handling checked vs. unchecked exceptions in worker threads? Should we always wrap checked exceptions in unchecked ones when working with thread pools?

Understanding these details would help explain why Java's exception handling mechanism is designed this way in multithreaded environments.
