I'm an undergraduate of University of Moratuwa, Sri Lanka. I'm interesting in fixing the bug of terminating execution of ROW_NUMBER() window function once criteria is met in Apache Derby Database Server which is described under this URL. But I couldn't find relevant codes in the source folder. I greatly apppriciate if you can provide some useful tips on ways to analyze the code.

Thank you,
