[kepler-dev] classpath too long

[David Welker]

Hi Jared,

I was wondering if you could replace your kepler-2.0.jar with the  
following jar that is attached named kepler-2.0-no-fork.jar. By not  
forking, it should avoid creating a long classpath. I have not been  
able to test this, but it should work. Please let me know if this  
solves the problem for you.

David
