A DESCRIPTION OF THE PROBLEM :
On the second line of the description there is a broken link in the text "(refer to How to Use Threads for more details)". It attempts to navigate to "http://download.oracle.com/javase/tutorial/uiswing/misc/threads.html" but displays a page saying 'Sorry'.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The link to go to the correct page.
ACTUAL -
Link can't be found as it points to a page that used to be on Suns website. Because Oracle no longer supports the Sun website, navigation and search has really go in the pits. So many things can't be found - through the site's search, or through Google (which is the normal 'Holy Grail').
