It's packed in the src.zip/src.jar that comes with the JDK.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
On this page at java.sun.com you will find a link for getting the 1.5 source code. Registration with Sun and agreement to a simple license is all that is required. Earlier versions of Java included src.zip with the download - I guess it has just gotten too bulky. The src.zip for 1.5 is 56MB - note that certain security related classes are a separate download.
