I just upgraded from v211 to v219. When trying to build, the Archiving step
takes an extremely long time now. Wheras it used to take a few seconds for a
23M WAR file to be archived, it now takes about 2 hours+

Here's the relevant log file message on which occurs right before the archiving:

[HUDSON] Archiving /c01/hudson/data/jobs/Dealer
Inventory/workspace/caps/caps-web/target/caps-web-1.0-SNAPSHOT.war to
/c01/hudson/data/jobs/Dealer
Inventory/modules/com.ca.caps$caps-web/builds/2008-05-29_15-40-30/archive/com.ca.caps/caps-web/1.0-SNAPSHOT/caps-web-1.0-SNAPSHOT.war

Note that this is a native Maven project.

Reverting back to v211 solved the problem.
