> when i make myself checker, i have to change the forehead.conf to add my jar file to the root class loader, otherwise, when i put the jar file in my project.xml dependency list, the plugin show me the error "Unable to create a Checker: cannot initialize module TreeWalker - Unable to instantiate net.zhyang.checkstyle.ConstantsCheck".
> I think the reason is the checkstyle always try to find class in same classloader(root classloader). if you put your checkstyle.jar in the root classloader, i have to put myself custom checker in the root classloader.
> And the
>       <properties>
>         <classloader>root</classloader>
>       </properties>
> is also deprecated,if you run under debug, you can see the warning message about it, it's the time to remove it from project.xml.
> after i removed them, i can run myself checker.
