I can tell you this much: the Exception statement starting on this last 
line ("Tcl -eval: ...") always occurs when running Swarm models in 
Eclipse, so you can ignore it.

It looks to me that you have Eclipse set up correctly; otherwise you 
would not have gotten the control panels. The Null pointer exception 
error could be real- could you somehow be trying to use a variable that 
has not been initialized?

Off the list I will send you a version of heatbugs that works for me.
