I'm not sure how to interpret message #47.  Maybe best for me to take a shot at
a fix and then for you to critique it.

We know one situation that can result in the NOPLoggerRepository warning, the
undesirable reloading and reinitialization of classes in
WebappClassLoader.clearReferences.  As that scenario is described, it seems
like there is little potential for resource leakage or other issue that should
concern a site admin, so the message could be dropped to a LogLog.debug() or
similar which would likely be suppressed.

However, we can't say that all situations that can result in the
NOPLoggerRepository are as innocuous.  So we don't want to lower the severity
in situations where we can't identify.  In those cases, we've got an obligation
to let the admin know that log4j has a serious problem and can't perform as
would be expected.  Maybe sometimes the NOPLoggerRepo message does occur
because of misconfiguration or unterminated threads, if those cases occur, we
shouldn't hide the info from the admin.  Comment #38 touched on the need to not
hide problems from admins that might let them know that things are going south.

There is a compromise here and it won't be perfect, however hopefully we could
eliminate a lot of unnecessarily scary messages to Tomcat admins that don't
reflect a potential stability issue while still informing other uses when we
feel that our stability has been compromised.
