How do I close a running JEP instance from another thread?

[balck-paint]

I need support to force end a running JEP instance from another thread is prompted: Unable to end from a non-starting thread. How to force an end? I tried closing the java thread running that instance, but alas, the py program was still running. What should we do now? Because in my use case, there may be scripts that have been running for a long time, but in some cases I want to end all scripts run by this user, such as when deleting a user

There is no way to close a running JEP instance from another thread. #263 has some related discussion.
