    Don't know whether this a problem in Artifactory itself or a Jetty bug. The exception occured while importing a rather large repository exported from Artifactory 1.2.5 using the 'artadmin' commandline tool. Not sure whether the import really succeeded. Artifact count in the web interface is still increasing, maybe the import is running in a background thread or count gets adjusted while the indexer tries to catch up). Commandline client immediately returned after the exception, printing "import finished in XXX seconds" (see stdout output below stacktrace). -------------------------------- 2009-12-07 12:19:49,590 [pool-1-thread-4] [WARN ] (o.m.log :76) - header full: java.lang.NullPointerException 2009-12-07 12:19:49,665 [pool-1-thread-4] [ERROR] (o.a.r.r.s.StreamStatusHolder:96) - Cannot send status to client.
