-------------------------------
Status: Resolved (was: Patch Available)
Assignee: Jukka Zitting
Fix Version/s: 2.1.0
Resolution: Fixed
Thanks for the excellent work on this! I've committed the latest patch and the
test case to Jackrabbit trunk in revision 933646 and merged the changes to the
2.1 branch in revision 933662. Is there demand for also a 1.6.2 release with
this fix?
