I'm having the same problem.  It looks like this has been discussed on -STABLE,
-JAVA, -HACKERS, and -QUESTIONS, but to no avail:

<http://www.freebsd.org/cgi/getmsg.cgi?fetch=437107+0+/usr/local/www/db/text/2002/freebsd-bugs/20020519.freebsd-bugs>

I'm sorry for the redundant cross-post, but this looks like a hard one to
solve.
