Thanks for bring this to my attention. I'm not sure if it was the cause of the crash but I can at least ensure that it will not be based on nz.co.lolnet.james137137.FactionChat.FactionsInfoServer.FactionInfoServer$ThreadListenForClients.run(FactionInfoServer.java:52),

Fixed. Thanks again. I'll try and release an update on dev.bukkit later tomorrow (NZ time)
