FWIW, we run Mauve in a very similar manner on builder.classpath.org:

exec > Log.Std 2>&1
./configure --with-ecj-jar=/usr/share/java/ecj.jar --with-vm=jamvm &&
make &&
xvfb-run jamvm Harness gnu.testlet -vm jamvm -showpasses -timeout 180000

(this is testing jamvm instead of java, and uses xvfb-run to avoid
needing an X display).

I did run Mauve a while ago on OS X and I don't remember having any
problems.  Things may have changed though.

I believe twisti has done a lot of recent work on the harness, but I
don't think it's committed yet.
