QuarkusDevModeTest freezes when it fails during the loading

[danielezonca]

Describe the bug
I just discovered a problem with Kogito Hot Reload test. When there is an error in an upper module, the test fails during the loading because of missing -deplyoment package but it freezes and then the build will reach the timeout and is aborted.
I did some analysis and created a PR to "workaround" it (see link) but I think it should solved also in Quarkus.

We have hot reload tests in a dedicated module instead of inside -deployment and we had no maven dependency on deployment module (because QuarkusDevModeTest loads the modules independently without using project configuration). The current fix is to declare the dependency so the module is skipped if deployment is not properly built.

I looked for a suggested configuration of hot reload tests from a different module but I was not able to find any so I guess my fix is correct (declare dependency on deployment) but still the build should not freeze in case of wrong configuration.

Expected behavior
Test fails and then build continue until the end

Actual behavior
Test fails during the initialization with this stacktrace but then freezes until build timeout (see last lines of the gist)
