Unfortunately, this doesn't work on our FreeBSD 7.0-RELEASE system (I
haven't checked this with a FreeBSD 7.2-RELEASE install yet).

The first compile/bootstrap of openjdk6 using the Diablo javac compiler
is fine.  Afterwards, I wanted to reinstall with other options, that is,
with and without IPv6 for testing purposes.  This failed (repetitively,
also after make clean) when the OpenJDK javac compiler was put to use, e.g.

# Running javac:
/usr/local/diablo-jdk1.6.0/bin/java -client -Xmx896m -Xms128m
-XX:PermSize=32m -XX:MaxPermSize=160m
-Xbootclasspath/p:/usr/ports/java/openjdk6/work/build/bsd-i586/langtools/dist/bootstrap/lib/javac.jar
...

When I remove the /usr/local/openjdk6 directory, the openjdk6 port
reinstalls without any problems, but using the Diablo javac compiler though.

I can post the compile errors if someone wants to dive into this to
figure out what is going wrong.
