Thanks @markhamstra for the explanations. I think currently the thread just
dies and we log the uncaught error. I can add a catch for NoClassDefFoundError
and handle it the same way as ClassNotFoundException. But even with that, I
think it's still better to inform the scheduler in finally to make sure the
failed task is handled. Let me know what you think.
