Crash in JHeatbug javaswarm.dll?

[Raynier van Egmond]

Dear All,

 

I am trying to get going with Swarm but am finding some nasty problems on the road.

 

I am working with Netbeans as the Java IDE and have the JHeatbug program compiling and "running" (almost).

 

All the correct settings have been made: path to the C:\Swarm-2.2.1\bin directory, set swarmjar on my path and mounted it in NetBeans. All that works fine. I confirmed this with an mail in the archives from http://www.santafe.edu/projects/swarm/archive/list-archive.0107/0143.html

 

However when I hit the start button the program crashes with an error "The Memory could not be written" and a stack dump as given.

 

Exception drawSelfOn: Heatbug
java.lang.NullPointerException
        at com.c3ismc.simul.swarm.sim.jheatbug.HeatbugObserverSwarm.buildObjects(HeatbugObserverSwarm.java:242)
        at com.c3ismc.simul.swarm.sim.jheatbug.StartHeatbugs.main(StartHeatbugs.java:42)
Exception in thread "main" 

 

When I comment out the offending, line the program crashes a little later - same problem... when it gets to address level failures it gets a little out of my league I'm afraid.

 

System description:

----------------------------
Windows 2000 Prof

Netbeans:     3.3.1

Swarm:         2.2.1

 

 

Any ideas or help would be greatly appreciated!

 

Many thanks in advance.
