I'm pretty sure there were instances of
     private static final LOG =...
in the codebase in the recent past. The new CS rules may have caused them to be eliminated, but it was my understanding that we use "log" for instance loggers and LOG for static loggers, both of which are private final. That said, we might simply consider a global switch to the slf4j recommended pattern:

and use "logger" exclusively (note it's never final, so jibes with our rules). I will admit lowercase is a little easier on my eyes.
