This segmentation violation is an intermittant problem, but most likely appears after a incremental compiled TestProduct. I see the violation about 3 times out of 20 launches. I haven't been able to pin down the particular offending sources. The applet doesn't even get up and running within a quarter of a second the segmentation violation appears. The Java 2D TestProduct can be found at :

/home/lichtenw/JavaMedia/2d/TestProduct

Try removing some of the class files in classes dir, such as TestLayout.class and TestPanel.class. Recompile with gnumake, run with runnit.promoted.

I've also seen this segmentation violation while running the DitherTest and SimpleGraph (in JDK1.2X) demos and the hanoi applet from-
/home/lichtenw/JavaMedia/2d/tests/applets

nancy.schorr@eng 1997-12-05: I've seen this to with the JDK-1.2beta2-X and JDK-1.2beta2-Y. Very intermittant, I estimate it happens one out of 15 times using the SwingApplet demo.

nancy.schorr@eng 1997-12-06: The violation occurred 3 times out of the 25 tests using Brian's 2D applet compatibility suite.

Another way to reproduce the AWT-Motif segmentation violation, run the javabeans
beanbox, in the properties window click on fonts, change to bold, press done.
