What happened?

I've got two test-containers set up in my tests, LocalStack and MockServer. Both of them are configured withReuse(true) but for some reason MockServer container stops after tests are executed. I also noticed something else; when I start the containers in one process and run the tests in another process, LocalStack container works without any issue and stays running (next to Ryuk container) after tests are executed, but MockServer stops right after tests are done. I couldn't find anything helpful as to what could be the issue:

1. I created the container using directly GenericContainer class, same behavior.
2. I Replace MockServer with WireMock (via GenericContainer) and it behaves as expected (similar to LocalStack), stays running after tests are done in another process, and also respects the reuse flag.

Relevant log output

There's not much log, only one line (apart from the startup logs):
> 19:59:50.278 [,] [docker-java-stream--1211111146] INFO  w.infra.containers.MockServer - STDOUT: 2022-11-01 18:59:50 5.14.0 INFO stopped for port: 1080
