Thank you for the report.
I think that kaffe on Linux ppc would be a good thing, because Sun's VM 
is not avaible. I'm coding some Swing applications and I would like to 
run them on Linux ppc, too. Is there a way to do this?
I like gcj, but it lacks on Swing support.
I'm also interested in SWT, and I'm thinking about a migration from 
Swing to SWT, but it could be a really long work.
