Java API documentation, class BorderFactory (and others)

A DESCRIPTION OF THE PROBLEM :
Why do many of the links in the Java API to the Java Tutorial actually point to java.sun.com?

On the BorderFactory page of the API, we find:
"For further information and examples see How to Use Borders, a section in The Java Tutorial."

"How to Use Borders points to here:
java.sun.com/docs/books/tutorial/uiswing/misc/border.html

"How to Use Borders" is actually here: http://docs.oracle.com/javase/tutorial/uiswing/components/border.html

There are many other instances of this problem. Some links to the tutorials work, many do not. This is very frustrating for a new programmer. I have to go to the tutorial index page and start hunting around for what I want.

This should be a simple fix. Joseph Harrington
