Description of problem:
When debugging a problem it is common to use the log4j level adjuster
to change the logging priorities of a number of categories. A
developer may then make some code changes, re-deploy & restart the
server. At which point they have to change all the log4j levels again.
This cycle may repeat several times. What is needed is for changes
made to log4j levels to be persisted across server restarts, although
probably only when the 'debugMode' flag is set to true.
