Beginnen Sie mit JUnit5TestSearcher.java in den Zeilen 69, 85 und 110 und verfolgen Sie anschließend die Stacktraces durch TestSearchUtils.findTestItemsInTypeBinding. Reproduzieren Sie die Testsuche für das betroffene Projekt und ermitteln Sie, welcher Pfad in der Annotationshierarchie die gemeldeten NullPointerExceptions auslöst; erledigt ist die Aufgabe, wenn die JUnit-5-Testsuche ohne diese Fehler abgeschlossen wird.
