Interesting.  But it breaks the concept of "write once run anywhere", to set a platform specific font. My issue centers on how to make it work WITHOUT that hack.
As I mentioned, my program currently runs fine on MacOS, Solaris, linux, .....
I dont want any OS-specific code in my program (nor should I have to have any?!)

btw: thanks to markspace for his code, but I'm using AWT.
Kindasorta like Knute's code, but with plain Frame, not JFrame, as top.
