Bắt đầu trong SQLMonitor.java tại getConnectionProperties(SQLMonitor.java:113), sau đó lần theo createTask ở dòng 81 và doRun ở dòng 49 bằng stack trace khởi tạo được cung cấp. Xác định giá trị cấu hình hoặc kết nối nào là null và xác minh rằng quá trình khởi tạo monitor hoàn tất mà không có ngoại lệ này; issue không nêu thiết lập kiểm thử hoặc tái hiện nào.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
