I've tried the last 3 or 4 builds of this from Jenkins and they all give me the same PermGen space error when trying to enable the plugin and then it basically breaks the server startup process. I am using Spigot 1.6.2 but also have the problem on Bukkit 1.6.2

3.3.0 is still the only version of this plugin that works for me but is over a year old and I am tired of the ugly error it gives on startup.

This topic will be interesting for you http://forum.sk89q.com/threads/out-of-memory-errors.9568/

tl;dr ( from wiki http://wiki.sk89q.com/wiki/CommandHelper/ ):
"CommandHelper has relatively high system requirements compared to some plugins. If you find your server won't start, and produces java.lang.OutOfMemoryError: PermGen space errors, you may need to start java with the -XX:MaxPermSize=128M (or some other number that ends up working for your server)."

Thanks for the help and sorry for bothering you in this location. I looked to an explanation but obviously didn't look very well.

As I know, LadyCailin already make solution and now it needs tests.
