default fonts for java applications?

[mmiller3@iupui.edu (Michael A. Miller)]

I'm running ImageJ (http://rsb.info.nih.gov/ij/) using Sun's J2SE
v 1.4.2, installed from j2sdk-1.4.2-nb-3.5-bin-linux.bin.  When I
start the application, the font used for the menu bar is big
enough that the menu items don't all fit in the window.  Can
anyone suggest a way to change the default font in this case.
The application itself doesn't specify a font - it just uses the
system default.
