We use a patched version of the 0.3.0-20061218 beta version of the deduplicator . The patches fixes the following issues in the NetarchiveSuite:

• [https://gforge.statsbiblioteket.dk/tracker/?aid=1062 Bug 1062] Indexserver skips a lot of lines due to threading problem with SimpleDateFormat

• [https://gforge.statsbiblioteket.dk/tracker/?aid=1078 Bug 1078] DeDuplikator index too large
