There's a guy on a mission to change all links to Java documentation from old version to Java 6 or 7 (the old documentation is not online any more). For example that one: https://stackoverflow.com/review/suggested-edits/3427037
Now, that may be correct but in some cases the new version of classes or methods may work differently so changing of the link will make change to the original meaning of the post. The frequency of edits suggest that they are not evaluated carefully.
Also, there's just so many of them coming - I'm not sure if it's a concern on its own. I guess not if all of them were correct.
I just wanted to bring it to attention here.
