Start with JUnit5TestSearcher.java at lines 69, 85, and 110, then follow the stack traces through TestSearchUtils.findTestItemsInTypeBinding. Reproduce test discovery for the affected project and determine which annotation-hierarchy path triggers the reported NullPointerExceptions; done means JUnit 5 test searching completes without these errors.
