After the service is stopped, the quartz automatic task cannot be stopped.

Environment:

The quartz automatic task is executed once every minute and an endless loop is executed. Deploy this project in node1. Start the node service to execute automatic tasks. Because automatic tasks are endless, they will not be stopped, and a thread will be started every minute for execution.

How to stop a quartz automatic task:

1. Try to stop the node node1 service of Websphere to see if the automatic task will stop. The result shows that the automatic task is still being executed.

Try 2: if we try to stop websphere, the automatic task is terminated.
