I know that this is just a workaround but you can use filter in your log4j configuration that helps ;) | <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> | <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/> | <param name="Target" value="System.out"/> | <param name="Threshold" value="DEBUG"/> | | <layout class="org.apache.log4j.PatternLayout"> | <!-- The default pattern: Date Priority [Category] Message\n --> | <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/> | </layout> | | <filter class="org.apache.log4j.varia.StringMatchFilter"> | <param name="StringToMatch" value="com.sun.facelets.compiler.TagLibraryConfig loadImplicit" /> | <param name="AcceptOnMatch" value="false" /> | </filter> | | </appender> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4118591#...
