What happened?

I'm trying to upgrade Micronaut Test Resources to test containers 1.19.2.

After this upgrade, one test is failing with:

Unexpected handshake request with client mechanism PLAIN, enabled mechanisms are [] (see https://github.com/micronaut-projects/micronaut-test-resources/actions/runs/6842478040)

This happens whenever on a test which requires to set an environment variable on the container:

https://github.com/micronaut-projects/micronaut-test-resources/blob/e527b06ac452e5c63348418386b5f24b899c377d/test-resources-kafka/src/test/resources/application-custom.yml#L6

So this all behaves as if the environment variable was ignored in 1.19.1. It also happens with 1.19.0, but the test passes with 1.18.3.

Relevant log output

Thanks for the report, @melix. It was fixed in #7748 and I have also added some tests related to sasl #7763. This is not released yet, but it will be soon.
