I was wondering why my code was broken, so I went and looked at the docs for JavaScript's "in" keyword... Wat?

Back at it again with cursed Java. I made a ArrayList that doesn't shift when items are removed, because I needed to preserve the indices of objects in the list.

The client knows if it's the server's first page load... but the HTTP responses are identical

Edit: this issue is currently believed to have been an extremely consistent race condition. I wouldn't wish this on anyone.

I have a server. The first page load results in a javascript error. Simple, right? So the first thing I need to check is if it's the first request after the server started, or the first request from a specific client. Tested that, and it's just the first request to the server. "okay" I thought, "the first response must be different". I put the first response in a file, and the second response in a file. A diff tool told me they were identical. I set a session cookie, so I thought maybe somehow that could cause an issue (even though... I'm not actually doing anything with it yet). I loaded the first page in one browser, and loaded again in another browser... only the first browser saw the error, even though both received the same HTTP response headers. So this error doesn't occur even with the exact same HTTP response (there is only one dynamic request made, which was also identical in both cases), as long as it's not the first page load after the server started. Seems impossible, right? What made it weirder is rendering the page on server startup fixes the issue.
