launching Java2Demo without having to preset JAVA_FONTS gets a segv

Build : java full version "JDK-1.2fcs-I"
app : Java2Demo /usr/local/java/jdk1.2fcs/solaris/demo/jfc/Java2D
Machine : name:mipmap hw:sun4u
OS : SunOS 5.6
bit depth : 24bit

cmdline : no parameters.

Without having the JAVA_FONTS set to a specific directory, simply launching Java2Demo causes a segv.

Abort

Then upon setting JAVA_FONTS to /usr/openwin/lib/X11/fonts/TrueType
will remedy the problem.
