Hello Lee,
although it's not a 2D question, I'll try to answer. The exception
indeed happens on 1.3. It doesn't occur on our next release which is
still under development.
It might be related to bug
4337825 getControlDarkShadow throws NullPointerException when printing.
(at least, it have the same stack trace there)
Anyway, it's not a good idea to add a swing component into a
heavyweight container - that's a recipe for lots of layout and other
problems.
One way to avoid the exception would to be using JApplet instead of
Applet:
public class Test1 extends JApplet
{
public Test1()
{
}
public void init()
{
getContentPane().add( new JButton("my button") );
}
public void start()
.....
Thank you,
Dmitri
