A related question was asked quite a long time back on StackOverflow. While no answer was provided on how to detect and migrate to newer (and possibly accurate) links, there is a bigger problem with respect to answers that contain nothing but the links.
In this case (of Sun forums being migrated to Oracle forums), answers that posted the contents of the former are in a reasonably better shape, than one-liners that merely linked to some forum thread. Should all one-liner answers containing dead links be flagged in case no alternatives are found?
Examples that I found:
There are possibly many more going by the Google search results, but not all of them will be the dreaded one-liners.
I attempted to find answers in the following posts on Meta, but only ended up getting confused.
- Should answers which contain only dead links be removed?
- Should we be using archive.org links to replace dead ones?
- Does an (old) answer that contains only a dead link deserve a downvote?
The (only) answer in the first question does not apply to the current situation. The second does not apply, for archive.org does not appear to have cached the contents. And the third will make me a much hated individual.
