[slf4j-user] Receiving strange exception - Level number 40 is not recognized.

[Jeffrey Puro]

I am receiving the following stack trace when trying to use slf4j within
JBoss AS 4.0.  I am using 1.3.1 with commons logging 1.1.  I'm guessing
it has to do with some dependency issue, and perhaps an older logger
implementation.  Thanks in advance.
