code: protected Comparator<RequestMapperBean> newComparator()
  	{
  		return new Comparator<RequestMapperBean>()
  		{
  			@Override
  			public int compare(final RequestMapperBean o1, final RequestMapperBean o2)
  			{
  				return o1.getCompatibilityScore() - o2.getCompatibilityScore();
  			}
  		};
  	}
docs: Factory method for creating a new Comparator for sort the compatibility score. This method is
  invoked in the method initializeRequestMappers and can be overridden so users can provide
  their own version of a Comparator.
  
  @return the new Comparator.
