JUnit tests fail with java.lang.InternalError: no stack frame matched test class #306
Description
Sometimes, unit tests (JUnit 4 via Gradle) fail with the stacktrace below. This does not happen everytime, as far as I can tell.
Test failure on CI: https://github.com/getappmap/appmap-intellij-plugin/actions/runs/18888383411/job/53909609198#step:6:2394

This happens when the test fails by rethrowing an exception raised in another thread. In this scenario, the test itself is not in the stack trace of the exception, which causes this error. #307 should fix it (once I get it to pass CI). You're welcome to grab this code and verify — I was able to reproduce the problem reliably by modifying the test in question to always fail by changing the expected value.
