The logging API should support optional parameters E.g.:

/**

• Issue a log message with parameters and a throwable with a level of TRACE.
  *
• @param loggerFqcn the logger class name
• @param message the message
• @param params the message parameters
• @param t the throwable
  */
  public void trace(String loggerFqcn, Object message, Object[] params, Throwable t) { ... }
  
  The logger factory method should allow specification of a resource bundle, e.g.:
  
  Logger getLogger(String category, String resourceBundleName) { ... }
