Class with multiple loggers

Reports classes that have multiple loggers declared. Ensuring that every class has a single dedicated logger is an important step in providing a unified logging implementation for an application.

For example:

  public class Critical {
    protected static final Logger LOG = Logger.getLogger(Critical.class);

    protected static final Logger myLogger = Logger.getLogger(getClass());
  }
