[logback-user] Mismatch error version from 1.5.4

Hello Alex,


You are using logback 0.9.9 which was compiled against SLF4J version
1.5.3. SLF4J version 1.5.4 is just letting you know that there is a
potential version mismatch, because logback-classic 0.9.9 does not
contain version information.

In this particular case, SLF4J cries wolf and you can simply ignore
the warning. The warning will disappear with the release of logback
0.9.10 in the coming days.

Coming to think of it, crying wolf this way, will be a constant
headache for outside SLF4J native implementations. e.g. Jboss. We'll have to 
come up with something less intrusive.

Anyway, hope this helps,
