带有awaitTermination的java.util.concurrent.RejectedExecutionException

Question

我有像这样的并行执行设置

java.util.concurrent.RejectedExecutionException: Task ExecutorService$2@5486ec58 rejected from java.util.concurrent.ThreadPoolExecutor@7b993426[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 4]
at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2047)
at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:823)
at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1369)

当我部署代码时，我遇到了这个异常：

{{1}}

当我删除.shutdown（）时，我没有问题，但它会阻塞，直到1秒钟结束。关于导致这种情况的任何想法？
