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

[Christopher Moesel]

Hello,

 

I've been using SLF4J 1.3.1 with jcl104-over-slf4j and Logback 0.9.5 for
a while.

 

Last night I upgraded to SLF4J 1.4.3 with jcl104-over-slf4j and Logback
0.9.8.  Now I am receiving the following stack traces:

 

java.lang.IllegalStateException: Level number 20 is not recognized.

org.slf4j.impl.JDK14LoggerAdapter.log(JDK14LoggerAdapter.java:529)

bstractApplicationContext.java:305)

            at

            at
org.springframework.context.support.ClassPathXmlApplicationContext.<init
>(ClassPathXmlApplicationContext.java:75)

            ... (rest snipped off)

 

I've googled and searched the mailing list archive, but I can't seem to
find how to fix this.  Especially since it looks like the logging
statement is not coming out of my own code, but rather, from Spring.
Any help would be greatly appreciated as I'd really like to upgrade and
use the MDC.

 

Thanks,

Chris
