Bắt đầu với JUnit5TestSearcher.java tại các dòng 69, 85 và 110, sau đó lần theo các stack trace qua TestSearchUtils.findTestItemsInTypeBinding. Tái hiện việc phát hiện test cho dự án bị ảnh hưởng và xác định đường dẫn nào trong hệ thống phân cấp annotation gây ra các NullPointerExceptions đã được báo cáo; hoàn thành khi việc tìm kiếm test JUnit 5 kết thúc mà không có các lỗi này.
