The problem is the Minecraft UUID System was not considered for NoPremium people and you know that Minecraft Servers must run in Offline mode for working with BungeeCord. When a Premium person logs in with an offline server or a BungeeCord IP, because the server is on Offline Mode the server doesn't interpretate the UUID and thinks that's the player name or something like that (24.05.2014 16:51:54: User fab3a7e6-ce0b-317a-b39c-b73eff556e59 not found!!!). Hope this is fixed early because it could affect all BungeeCord Networks.
ADVICE: This is a minecraft server problem with Offline Mode, not with BungeeCord. This also happened when I put someone on the Whitelist or in the OPs list.

Yeah, you are right, but then, why the server.properties has this option? I think this must be fixed because is not only the people that doesn't bought the game, think if you join through a Proxy you have to be on offline mode. The plugins using player data will not work (including Whitelist and OPs) because is on Offline mode. There are two solutions: deleting the Offline mode or fix this
The third solution is to run Minecraft the way it was made. Vanilla servers work fine. Your bug report specifically pertains to third party plugins. Mojang cannot help you.
This is not a Minecraft server problem. This is a problem with a third party program as well as what I can understand affects those who haven't purchased that game? Invalid.
