    So can someone explain what the exploit was, because i got banned from a server because it went down while i was there, i hadnt done anything, but this might be the answer to why i got banned.

    Just out of curiosity, what does the 646 when you type 'version' mean? It's confused me for so long, and I just now realized it wasn't the version number! :p

    You're better off posting in the topic for that specific plugin. This isn't a support topic.

    Can someone please explain how plugging an exploitable hole causes the .jar file to explode in size by 400%? Apparently that 'hole' was big enough to waste code the size of 4 entire craftbukkit implementations. You guys sure you didn't get it the other way around and put a trojan back in it instead? :eek:

    I'm asking since 6+Mb of 'exploit-fix' code on a 1.5Mb app kinda makes my neck-hairs rise, while I'm sure there is also a reasonable explanation, right?

    EDIT: I know this question has been asked at least 2 times before in this thread; I'm not trying to hammer; I just expected to see a satisfactory answer already, but sadly a proper explanation has not yet been given. I think it's a very reasonable question deserving of an answer, especially given the security-concern with which this patch was presented.

    I wonder why people think 14mb is so big?

    The CraftBukkit Snapshot file should replace your current server file (the one your run to start your server) and should not be in the plugins directory.

    The strange thing is,.. when I download this #670, the version on my server says #646.

    Lol I don't have it in my plugins folder! :)

    Hmm, that's weird then, in the error it says

    I can send you a screenshot it's NOT: in the plugin folder ;)

    You could always just look into the jar file and check what is in it to find out.

    The new bukkit jar e.g. includes sql-lite (which has at least ~3 MB packed size) and other libraries that weren't in the previous versions. These will be needed later for Permissions and Persistence.

    You do. Remove it from your "plugins" folder. It's up to you to find the right one, on the right server though.

    Ever since 602, CraftBukkit actually spams my console with "Can't keep up!" messages which I NEVER had before on my very powerful quad-core serever with 16 GB RAM and stuff like that.

    Even though it shows a lot of these messages, I still can hold a lot of players on my server. 30-50 players and no lag.
    But I really want these messages to go away soon.
