Thank you for the patch.  This is bug number 6604479:
   http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6604479

We discovered the problem during the test builds on b20 promotion day.  It
was decided to go ahead and promote, but also send email to build-dev at openjdk.java.net.

Here is the email thread:

    http://mail.openjdk.java.net/pipermail/build-dev/2007-September/000262.html

This build fix is in b21, which should be available today.
