like the kind of stuff I was talking about a couple of weeks ago; code that has no
real reason to only be on generics (and shouldn't have been developed there to start
with).

However, this won't solve the problem immediately as such a port would not be rolled
out until Classpath 0.91.  As Mark says, jamvm and classpath-generics is probably
your best solution for now, but you'll have to build the generics branch yourself.
Assuming you have a recent enough version of jamvm (presumably from testing or unstable),
you can get away with just pointing it at your local generics-branch install e.g.

mv /usr/share/classpath /usr/share/classpath.debian
mv /usr/lib/classpath /usr/lib/classpath.debian
ln -s $(generics_prefix)/share/classpath /usr/share/classpath.generics
ln -s $(generics_prefix)/lib/classpath /usr/lib/classpath.generics

This gives you both Debian's copy of Classpath, and the generics one respectively
as classpath.debian and classpath.generics in /usr/lib and /usr/share.  Then you
just symlink the one you want to /usr/lib/classpath and /usr/share/classpath and jamvm
will use it.

Alternatively, it shouldn't be too hard to build a local version of JamVM too, and point
it directly at your generics build.

Note that you'll need ecj to build the generics branch, but, with that on the path,
it should work out of the box with the usual ./configure; make; make install combo, giving
an appropriate prefix to configure.

Thanks for trying GNU Classpath!
