As I was having some problems with the extension, I created a blank dev container (java, bullseye-21), and clones the sample projects of junit5: (got directed there from https://code.visualstudio.com/docs/java/java-testing > https://github.com/junit-team/junit5-samples)  In the testing tab, no tests are being found. And no green arrows appear next to the tests:  Building it using mvn (not mvnw as it complains about _"cannot read distributionUrl property in ./.mvn/wrapper/maven-wrapper.properties"_) works fine:  All the while no tests are being found, and the extension is searching for tests for over an hour already (see first and second image).
