Redirect Java util logging (JUL) to Log4J/SLF4J

Looking carefully at not introducing an endless loop between JUL, Log4J and SLF4J, JUL messages should be redirected to Log4J or SLF4J.
Current logging libraries in Tomcat:
./lib/log4j-1.2.14.jar
./lib/log4j.xml
./nxserver/lib/jboss-seam-jul-2.1.0.SP1.jar
./nxserver/lib/slf4j-api-1.6.0.jar
./nxserver/lib/slf4j-log4j12-1.6.0.jar (bridge SLF4J => LOG4J)

Try adding ./lib/jul-to-slf4j-1.6.1.jar (bridge JUL => SLF4J)
