These are old failures. The goal for this bug is to be reopened each time there's a new otherwise uncategorized runtime.throw (instead of, say, creating a new bug pointing at a test in package strings or wherever it manifested), and then we make a more specific issue for it, and close this one. And then the next time there's an uncategorized runtime.throw, watchflakes posts and reopens. So I will close this one right now.

This is #54596 . I updated pattern there.

For this issue, does watchflakes suppose to reopen it as it found a new failure? @rsc
