docs: Log a method entry, with an array of parameters.
  <p>
  This is a convenience method that can be used to log entry
  to a method.  A LogRecord with message "ENTRY" (followed by a
  format {N} indicator for each entry in the parameter array),
  log level FINER, and the given sourceMethod, sourceClass, and
  parameters is logged.
  <p>
  @param   sourceClass    name of class that issued the logging request
  @param   sourceMethod   name of method that is being entered
  @param   params         array of parameters to the method being entered
