Cannot run test class with '$' in its name sometime.

Looks like the upstream test runner could not deal with this case decently.

I can see traces:

Beginne damit, den im Stacktrace genannten JUnit-Startpfad nachzuverfolgen, insbesondere JUnitLaunchConfigurationDelegate, JUnitLaunchUtils und TestDelegateCommandHandler. Reproduziere den Fehler mit einer Testklasse, deren Name '$' enthält, und vergleiche sie mit einer Klasse mit einem gewöhnlichen Namen. Als erledigt gilt die Aufgabe, wenn die betroffene Testklasse über den VS Code Java test runner ohne den gemeldeten Fehler 'No tests found' ausgeführt werden kann.
