The Windows implementation of the Java virtual machine is causing my
application
to flicker and continually repaint the screen.  From elimination, I
found
the problem to be the setFont call.  After I boil down my problem,
I have the following sample application which flickers uncontrollably.

As indicated by my debugging, the paint method of my class inheriting
from JFrame is continually called.

My Java version on Windows is JAVA version "1.4.2_05"

My Java version on Linux using VNC is 1.5.0_01 although I also tested
on earlier versions of Java on Linux and it did not flicker on those
versions.

Note, the application does not interact with the user--it just displays
some straightforward graphics.
