Continuous testing fails to run any tests due to ClassNotFoundException

Describe the bug

I'm getting the following exception when resuming/running tests:

SomeKey is just an @Embeddable from our register-core module. Dev mode is started in the register-server module and we have 6 other modules that the server module depends on as well.

I tried continuous testing various times before 2.4 and got similar exceptions, but mentioning other classes.
But since before 2.4 there was no way to run tests from upstream modules (and our server module has no own tests), the setup was a bit different there; dev mode was run in other modules that had test-jars in the mix, which is probably not directly comparable.

Expected behavior

No exceptions, test should be executed.

Actual behavior

ClassNotFoundException

How to Reproduce?

So far I have been unable to reproduce this with smaller setups and my project is closed source.

@stuartwdouglas asked me to create an issue regardless: https://quarkusio.zulipchat.com/#narrow/stream/187038-dev/topic/PR.20Review/near/255134078
