Loggers initialized with foreign classes

[timveil]

I found a number of instances were a Logger class is initialized with a class name other than the class in which it belongs. This is typically unintentional and caused by copying logger initialization from one class to another. Creating this issue to track the PR to correct these instances. Here is a likely example...

public class SpecialValueTransformer implements RecordTransformer {

  private static final Logger LOGGER = LoggerFactory.getLogger(NullValueTransformer.class);
  ...
}

in this instance the LOGGER should have been initialized with SpecialValueTransformer.class instead of NullValueTransformer.class
