• Answer:

  I too downloaded the most recent edition of Craft Bukkit and was having the same errors as you (1.1 R-6) After looking for answers and realizing that it really only just came out and not many people have had the problem I checked to see what could be the problem. My troubleshooting steps were these: - Download 1.1 R6, start it fresh to see if I receive the error. (Started fine, created worlds, no error) - Looked through the errors and noticed that the error comes after (Implementing API version 1.1 R-6), scrolling a bit more found it said org.bukkit.craftbukkit.CraftServer.loadP… this led me to believe it could be due to outdated plugins, I copied and pasted my plugins folder over to find that it caused the start up error. - I deleted all of my plugins except WorldEdit, the server was able to start, but could not start WorldEdit. Conclusion: Most of your plugins are outdated, please search for updates using dev.bukkit.org and do check if they are compatible with v1.1 R-6 because if they are not, then more than likely they will not allow the server to run. Or you could just run CraftBukkit 1.1 R-6 with no plugins, but where's the fun in that? Happy minecrafting!
