This may just be an unavoidable side effect of the new UUID system on servers, but If whitelisting and offline mode are on, the server will reject every player that tries to connect. It shows up in the server log as "You are not white-listed on this server!" This persists even after reloading the whitelist or restarting the server. I would assume that this sort of thing is what the new "usercache.json" is for?
Edit: In 14w10b, whitelists worked as long as the server was in online mode. As of 14w10c, whitelists don't work even in online mode.
Edit: It seems that when the snapshot converted all of my server files, it looked up the incorrect UUID for myself. It then stored said incorrect UUID in the user cache. To fix the problem. Simply delete the usercashe.json file and let the server re-create it on restart. Still doesn't work for offline mode.

I have the same issue as well. I've tried Player Names, UUID, and IP addresses... nothing. Do I have to put inside those new brackets that show up if you do a clean server install, or what?
figured out how to add myself with the new UUID lol just used the server commands in the server console to add myself and others on my server as OP and whitelist... works perfect now for ONLINE... I'm not sure about offline
Offline servers and whitelists/bans/ops/any kind of list makes no sense, anyone can be anyone at any time. This is not supported behaviour by us, and it will not work for offline servers.
This is just in case my question was misunderstood (which I think is unlikely, I'm not trying to be that user that is whining about his issue). I understand that an internet connection is absolutely required to edit whitelists/op list/etc., as the server must look up the appropriate UUIDs. My bit is that as the server stores the UUIDs, somebody who is opped or something should still have those privelages if the server is running without an Internet connection.However, I understand that this is an issue that effects a very small number of people, and I can probably find a way to make it work if I have to. You're still awesome, Mojang.
Same here.
Impossible to use whitelist or Ops list, not player name or UUID
affected on 14w10c too
