---------------------------------------

Hi Dominique,

Good point! When this patch is applied to a Jackrabbit installation that already uses the
clustering feature it will break if the LOCAL_REVISIONS table is not added manually. I'll
look into this.

> The revision table in which cluster nodes write their changes can potentially become
very large. If all cluster nodes are up to date to a certain revision number, then it seems
unnecessary to keep the revisions with a lower number.
