Java processes keep running after Zowe job is stopped

[arxioly]

APIML java processes are still working after graceful (using /P) shutdown of Zowe.

Steps to reproduce:

1. Start Zowe using /S
2. Wait for the API Catalog to be available
3. Stop Zowe using /P
4. Check for runnning java processes under Zowe user in USS by issuing following command:

ps -ef | grep java

Expected result:
Zowe Launcher stopped all Zowe processes.

Zowe version: 2.9.0

@1000TurquoisePogs @struga0258 we can reproduce this if you need @ifakhrutdinov ... I can reproduce java code staying around after zowe dies even in the absense of the launcher (when, in development, sometimes i run zwe directly under USS and manage the processes myself)

@arxioly can you please upload the full logs of the launcher and the affected Java components? Ideally in cases when this happens and doesn't happen.
