According to the docs on NoClassDefFoundError:
Thrown if the Java Virtual Machine or a classloader tries to load
in the definition of a class (as part of a normal method call or as part
of creating a
new instance using the new expression) and no definition of the
class could be found.
The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.
When I encountered this problem recently I found that I had a problem with my classpath: the class the complaint was about (in your case it'd be X11GraphicsEnvironment..) was in two different packages in my classpath. I changed the code for the reference of that class and I was ok then. (Make sure you "build all" too..)

Geeta
