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
[https://gforge.statsbiblioteket.dk/tracker/?aid=1248 Bug 1248] NPE in deduplicator-0.3.0-20061218b.jar

Note that the deduplicator must be compiled with the same version of heritrix as the NetarchiveSuite uses, or the deduplicator will fail to work during runtime.
