org.jboss.logging.util.OnlyOnceErrorHandler no longer implem

[oyenstikker]

As of 4.0.2, org.jboss.logging.util.OnlyOnceErrorHandler no longer implements org.apache.log4j.spi.ErrorHandler. Yet the log4j.xml assumes it does. Why is this?

What makes you think it doesn't implement the interface?

I have just looked at the history in CVS and every version does implement the ErrorHandler interface.

The javadoc didn't list it. I just looked at the code, which does implement it. I compiled from that code. I still get this when I deploy my .war (which works just fine in 4.0.1):

Do you have a log4j.jar included in your WAR file? This may be the cause of the trouble - try removing it and redeploy.

See this for an article pointing in that direction: http://www.myeclipseide.com/index.php?name=PNphpBB2&file=viewtopic&p=35304
