It seems the GlassFish updater has an issue where it is reporting a
successful upgrade,
but fails to update the classpath-prefix of the domain.xml.
We've removed the updater from the download section for the time being
and have updated the
'Known Issues' section of the live release notes with a brief
description of the problem and
how to upgrade manually.
Please see the last bullet on this page for details:
