@prrace I don't think it is reasonable for you to blame @sendaoYan for integrating. He had a review from a Reviewer, and he waited 24 hours after that before integrating. The general JDK rule is that one review is enough; Hotspot as a special case requires two. Your comment did not say that you wanted to review it further, nor did you clearly request any changes, just a vague idea of replacing realpath with a strcpy (which seems like much more risky, and potentially incorrect, change!)

The responsibility for this PR is mine. I had reviewed and approved the PR. I did consider if I should increase the number of reviewers and state that a client team reviewer was also needed, but decided against it. That was my decision as a reviewer. The PR was clearly unproblematic. It added some extra logging in case something gets terribly wrong. Without this fix, AWT would just break without any indication whatsoever if something did go wrong with realpath. With this fix, this unlikely problem will at least get some indication. I did not think this needed confirmation from the client team as well.
