It's certainly possible, but I have no idea whether it happens often
while running Java programs on Kaffe.

I keep coming across problems like this -- questions that can't be
answered without detailed knowledge of object-allocation patterns in
Java (or other languages, for that matter).  So, does anyone know if
there's a study of Java object demographics available anywhere, and if
so where?

If there isn't, then can anyone point me to a source of Java programs
that I can run and analyse?  (If they're not graphical then so much
the better -- easier to run automatically.)
