Plugin error/command bug (Mac OSX)

(MAC OSX)

Hello.

I'm hosting a server for me and a friend so we can play together. I'm up late and wake up late and he wakes up early. He's always asking for me to turn on the server or to have it on at night so he can play when he wakes up. If the server is on, I play Minecraft and use Opera (which takes a lot of RAM itself), I almost use up all my 6 GB of RAM.

Therefore I decided to download craftbukkit on my iMac, which I can have on longer than my gaming PC, which I turn off when I go to bed. It took me a while to get the IP right, but I believe I figured it out - atleast it works.

ENOUGH RAMBLING, I'm sorry

I'm having a couple of problems. First off, the two plugins i'm using doesnt work. Java is updated, both plugins are updated and also craftbukkit. They work on my gaming PC, but for some reason not on my iMac. I thought plugins worked, despite what OS you use (if craftbukkit works), but I might be wrong. Here's my error:

The other problem I have is the /stop command. When I use it, all it does it restart the server and I have to use it again for it to stop. Is this intended or a bug?

Hopefully this is enough for someone to help me. Just ask if something is needed. Also, sorry for all the rambling at the start - for some reason I always to that.

BYE!

 

I have been having the exact same error message when i try to load any plugins other than permissions, planetoids and observer!!! SOMEONE PLZ HELP!!

 

Possibly you could get Windows on Boot Camp, and host it from there? Other than that, I'm clueless. I'm having the same problem on stupid Leopard. I even reinstalled it. No success. I would get a used PC, with at least 2GB of RAM, and host it from there.

 

what java version do you have on pc and mac?
