>            Reporter: Colin McCabe

> Now that we are using both commons-logging and slf4j, we can no longer rely 
> on just casting the Log object to a {{Log4JLogger}} and calling {{setLevel}} 
> on that.  With {{org.slf4j.Logger}} objects, we need to look up the 
> underlying {{Log4JLogger}} using {{LogManager#getLogger}}.
> This patch adds {{GenericTestUtils#disableLog}} and 
> {{GenericTestUtils#setLogLevel}} functions which hide this complexity from 
> unit tests, just allowing the tests to call {{disableLog}} or 
> {{setLogLevel}}, and have {{GenericTestUtils}} figure out the right thing to 
> do based on the log / logger type.
