[slf4j-user] jcl104-over-slf4j on the web's classpath causes redirection of tomcat's internal logging

[Ceki Gulcu]

If my memory serves me correctly, 5.5.17 has a "feature" whereby it clobbers all 
references to static variables when a web-app is reinitiialized. This has the 
side effect of killing any SLF4J binding. But, this may or may not be related to 
the problem you describe.
