[error] (aws-spi-pekko-http / Test / definedTests) org.junit.platform.commons.JUnitException: TestEngine with ID 'junit-vintage' failed to discover tests

The error does not happen in scala 2.12.20 or 2.13.14. It only happens in scala 3.3.3

If I understand junit-team/junit5#401 correctly I think the JUnitException is expected...

The workaround was to rewrite the code to use less inner/anonymous classes...

Forgot to mention that it only happens in java 8. In my case it was

$ java -version
openjdk version "1.8.0_412"
OpenJDK Runtime Environment Corretto-8.412.08.1 (build 1.8.0_412-b08)
