[slf4j-user] java.lang.IllegalStateException: Level number 20 is not recognized.

[Christopher Moesel]

Hi Ceki,

I didn't think I had jcl-over-slf4j 1.3.1 in there, but I'll check.  I was just thinking about it though-- I am using Maven with the jetty:run plugin.  Is it possible that Jetty is bringing in the older version?

I'll try this out again this afternoon and see what happens.  I'll also try it in tomcat to see if that changes anything.

Thanks for the reply!
-Chris

Looking at the problem a little more, I suspect that you are using 
jcl-over-slf4j version 1.3.1 and slf4j-api version 1.4.x. Is that possible?
