[Tinyos] LossyBuilder

[Phani Kumar Arava]

I was checking out the LossyBuilder app to build the 'nss' file but i get
this error. I even updated from the CVS, Still I get this error


******************************************************************************* 

java net.tinyos.sim.LossyBuilder -t grid -d 16 16 -o lossy.nss
Starting NetworkBuilder.
Generating 16 by 16 grid.
java.lang.NullPointerException

***************************************************************************** 

And one more thing is that when  I give the command with -s 40 (greater 
than 40 it executes)

But its all weird result. Is there any bug in the program ?




Someone please help me, Where Am i going wrong ??
