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

[Jeffrey Puro]

I tried running a later version of slf4j, but the problem is that I'm running JBoss AS 4.0 and it has an older version of log4j bundled in it (which I'm having a heck of a time upgrading).  It appears that from version 1.4.0 and on slf4j requires a newer version of log4j.

Thanks,

Jeff

Jeffrey,

It seems to me like you are mixing various slf4j versions. The
internal representation of level changed between SLF4J version 1.3.1
and 1.4.0 when the trace level was introduced. Could you try using a
version of SLF4J later than 1.3.1? I would recommend version 1.5.0.

You might also want to check whether you are using different versions
of SLF4J simultaneously.

I hope this helps,
