   Is it because of https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/util/concurrent/ThreadPoolExecutor.java#L1061 ?
   {code}
   boolean timed = allowCoreThreadTimeOut || wc > corePoolSize;
   ..
   ...
   ...
     Runnable r = timed ?
                       workQueue.poll(keepAliveTime, TimeUnit.NANOSECONDS) :
                       workQueue.take();
   {code}
   
   However, allowCoreThreadTimeOut will be false by default. 
   
   So unless someone explicitly sets allowCoreThreadTimeOut(true), this condition should not happen.
   
   Can you share the logs when you observed 1 minute delay in shutdown?
