----------------------------------------
I will debug this more but I am not able to see what exactly is casuing a npe.
When I debug using eclipse, it is interesting that right when I get to

I simply get a NPE without being able to get into the method to see what is the
source of NPE. Maybe something is wrong with my setup of Eclipse but I was
wondering if anyone has little time to see if there are able to see where
exactly npe is generated. I have tried with both sane and insane builds.
