Hello and thanks for the PR! The current code uses the try-with-resources syntax: https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html

so the Cursor should be closed after using it. Do you have a scenario when you think the current code doesn't do that?

Thanks 🙂

Hello! Thanks for your answer

My bad, I wasn't aware that this syntax handled the closing.

I don't see any reason it would not do so, I'll close this PR 🙂
