In most projects there are certain parts of the source code which are edited by many developers. Tracking who made a particular change and why is not very easy. Eclipse in the recent build (3.2 RC5 (I do not know when this was introduced)) has a neat way of tracking this. Just right click on the Java editor and click on Source>Show Annotation.
Now take a look at the line number bar on the left. This shows a different color for each user’s changes. Just hover over it to see the CVS comments for this change along with the user name, version and time. Pretty neat.

What is frustrating is that you can’t see rev, user or change date on the left editor gutter area. Major reason for not implementing that is absense of common gutter API in Eclipse editors. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=85751
