I was hoping someone would have already bounced this thread, but I guess
There is a confirmed bug in JOSM 2417 that breaks uploading, and may
encourage users to inadvertently delete ways if the validator plugin is
It looks like there's a partial fix in 2439SVN, but the root problem may not
be completely fixed yet. Please see
http://josm.openstreetmap.de/ticket/3884 for the gory details.
I've not sure which group handles it, but I'd recommend at least adding a
note to the MOTD. If anyone else thinks it's critical enough, then it might
be necessary to set the server to blacklist any edits that come from 2417 as

I confirm the issue with 2417. I have it when downloading small areas along
my GPS tracks. A lot of ways come in "empty" (with 0 nodes) which causes
problems later for the validator and when trying to upload my work.
