Can't stop farm after error appears in farmBeforeIntegrationTest

[triffer]

I have a integration test that will start four webapps for testing. If an error (e.g. "java.lang.Exception: Failed to start component [StandardServer[-1]]") occurs during farmBeforeIntegrationTest the server won't be shutdown.
When I run farmAfterIntegrationTest explicitly after the before failed, this task will also fail with the following message: Gretty seems to be not running, cannot send command 'stop' to it.
I also tried running farmStop, but I got the same message.

I'm running into a similar problem - do you remember what the solution was?

There was no real solution, just a workaround. We had a shell script in our pipeline that stopped those processes when an error occured. Meanwhile we are using Docker.
