So this is essentially a (collection of) tweaked gcc41 port(s) that 
avoids the gmake bug that hoses systems with 1GB RAM? If so I'd love to 
try this, as I've been wanting to do the same for a while.

Harmony is not as mature as gcj+classpath is right now, in both the VM 
and class library parts. It has a very bright potential though. One of 
the nice things about us is that the current VM effort (JCHEVM) is a 
strip down version of ports/java/jc, by our very own archie.

The Harmony class library is currently not quite functional with the 
JCHEVM, but that is being worked on. It doesn't support FreeBSD at the 
moment, but that will undoubtedly change. I have a (rather old) WIP that 
I hope to finish sometime.
