I've done something wrong; Plugins Give Error (all of them)

Ugh, it's not that I'm new to bukkit or anything, i've used it for over 2-3 months. Anyways, since the last update 1.4 on Minecraft. I've gotten one error message that annoy me.

This is the one, what have I done wrong?...
This is an output I have for each plugin I install, I've downloaded the recommended version (#677) a couple of times. And I still got this, I even made a separate folder, still nothing.

I doubt it's my Java version, I'm using a rather recent update on Mac OS X. (Soon gonna get another unix based system with a intel i7 Extreme 990x)

I'm a pretty fluent programmer, but Minecraft and Java just isn't a field I've really bothered to discover yet.

Anyone with a fix to this will make me a big favor

PS: If anyone got some idea on hardware, could you give me some examples of motherboards and other stuff I should have with my Intel i7 Extreme edition 990x? Thanks!

EDIT: I forgot to say; I don't use any wrappers, I use Port Map for ports, but it should not interfere with incoming and out-coming data. This is on activation of Bukkit.
I use the architecture system x64 (64 bit).
No problems with native/vanilla version.

That error does not make sense if it is reported for all plugins...
Try a fresh (new doanloads and worlds) server in a separate directory, slowly add plugins, to see where the error starts.

 

Happens to most plugins. So far: I did test it in a separate directory, I only added one plugin when I tested it. The plugin said it supported #677

Anyways, I can always test more plugins but, five out of five plugins that says that it supports #677 have so far given me a error. I'll report back in 15-25 min or less.

 

I still do not get why it should do that... post the plugins maybe you really had bad luck in your selection ,.)

 

Well, 5 minutes. I found a plugin which works, I need to go and bug some plugin authors
Thanks for helping.

Hehe, yes I was unlucky with my selection
