Lewis John McGibbney commented on NUTCH-1188:
---------------------------------------------

Hi guys, I think it's critical that we get this one ironed out before we begin firing RC's.
Can we confirm that in our trunk 1.4 development code (and in Nutchgora branch) that this
has been sorted out previously and that it is only an issue in the now deprecated 1.4 branch.
Thanks

> LogUtil has static fields,which is initialized like this:
>     FATAL = Logger.class.getMethod("error", new Class[] { Object.class });
> but the Logger has no such method,the correct method is:
>     void org.slf4j.Logger.error(String msg)
> So,LogUtil's static fields are not initialized correctly(they are null)
