#2 JOGLPanel null pointer exception sometimes

[kristi]

Sometimes when i run the simulation, i get this
exception. I think it may be the JOGLPanel initizlizing
before Master finishes initializing, but i could be wrong...

I see the error, but the panel still runs. =P

JOGLPanel line 172:
for(int k = 0; k < master.numberOfObjects() && cnt < 8;
k++)

Console output:

corner: 0 0
