In the GUI for the Demo application, there is a text-field which shows the current
status of the simulated robots. It is supposed to change color depending on its
state: In-Motion/Green, Collision/Red, Detection/Orange, Halted/Gray.
The GUI behaves correctly under Java 1.1.8, but under the newer Java (version 1.3),
it remains gray all the time. Apparently, something changed in Java so that
what used to work no longer does.
After initial investigation, I am clueless as to what is wrong. I have observed
this behavior under windows and SunOS. Note that the affected GUI is
based on the AWT rather than Swing.
