hi,
i don't understand what you are trying to achieve here. the
jcr:frozenNode/jcr:uuid is the uuid of the frozen node - and i'm not
sure for what you use this?
however, there could be a problem deleting a version while you are
iterating of the them.
further i don't think that you can delete a version as long it's still
referenced as base version.
regards, toby
