code: public final String getAsShortText(ReadablePartial partial, Locale locale) {
          return getAsShortText(partial, partial.get(getType()), locale);
      }
docs: Get the human-readable, short text value of this field from a partial instant.
  If the specified locale is null, the default locale is used.
  <p>
  The default implementation calls {@link ReadablePartial#get(DateTimeFieldType)}
  and {@link #getAsText(ReadablePartial, int, Locale)}.
  
  @param partial  the partial instant to query
  @param locale  the locale to use for selecting a text symbol, null for default
  @return the text value of the field
