Can't download ANY Plugins

It says stuff like " null loading [mod] <Is it up to date?> java.lang.NullPointerException"
Then a ton of more lines

 

First of all, you can download, but htey do not run.
Secondly, post the whole error, not just "stuff like" please.

try removing iConomy

 

server works just not the plugin

 

If you have the 193 recommended release, go update iConomy and if still not working, go nag the developer.
