Adding logging levels for specific logging categories deosn't seem to work on anything below INFO.

Adding a <logger /> to the configuration with a custom logging level of anything below INFO, e.g. TRACE or DEBUG, seems to have no affect.

The following should log all hibernate messages, but only logs INFO and higher.
<logger category="org.hibernate">
<level name="ALL"/>
</logger>

The following should only log warning messages, which it does.
<logger category="org.hibernate">
<level name="WARN"/>
</logger>
