stop postgresql on shutdown not working

[RinatMoravia]

Hi,

I add to my code:
Runtime.getRuntime.addShutdownHook(new Thread(() => {
postgres.stop()
}))

I want postgres to stop when app stops. It does not happen.

I can see that stop is running, I'm getting to forceDelete - my temp folder.
It fails to delete my temp folder so it's trying to force delete on exist by adding it to shutdownhook (isn't it too late now?).
Then I get an exception that says:

Exception in thread "Thread-8" java.lang.IllegalStateException: Shutdown in progress

Process finished with exit code 0

Thanks,
