   > callbackExecutor，2cpu个线程，队列长度为50000，线程池拒绝策略为：AbortPolicy
   
   The `AbortPolicy` has no effect for `callbackExecutor`, because when `callbackExecutor` catch `RejectedExecutionException` in the external invoked thread, it does not throw  exception to the upper layer.
   
   As shown below:

   **So no matter which rejection policy is set for** `callbackExecutor`, **the final real policy is the** `CallerRunsPolicy`.
