I couldn't quite find anything that addressed this (I assume I searched poorly).
This old-ish question regarding Java's integer object caching got a new answer yesterday. I felt the answer completely missed the point of the question, duplicated information already contained in the accepted answer (and others), and actively detracted from the page by being noise.
I commented, hoping it would encourage the answerer to delete, or at least revise to address the fundamental question, but was met with... disagreement regarding the nature of the question. I'm almost certain my analysis was correct, but I didn't downvote the answer (yet).
For me, part of SO's value is as a repository. As such, I think gardening is appropriate (and necessary), and it vexes me when needless, (IMO) off-topic answers are given to essentially closed topics.
- What should I have done/do, if anything?
- Is there a reference that would give me further info?
- Is it just OCDish that I care about the One Answer to Rule Them All notion in some cases?
Edit I guess it's just a phase; a number of additional answers to old questions have popped up: bytecode, overriding main, overriding main again with the same answer, what does
main belong to (third mostly-identical answer), and more about bytes.
* I also just feel for the guy, which probably shouldn't enter in to it, but it's how I am.
