In sim.portrayal.inspector.PropertyInspector.java.

In the following code, notice the commented out errors.  If you uncomment them and rebuild PropertyInspector.java, it'll generate lots of errors on trying to load non-existent JFreeChart classes.

            try 
                { 
                _theClass = Class.forName((String)(classes.objs[x]), true, Thread.currentThread().getContextClassLoader());
                }       
            catch (ClassNotFoundException error) 
                {
                //error.printStackTrace();  // fail silently, it's annoying
                continue;  // no class, can't make menu
                }
            catch (NoClassDefFoundError error) // why does this even exist?
                {
                //error.printStackTrace();  // fail silently, it's annoying
                continue;  // no class, can't make menu
                }
