JWNL bug???

Hi,
   I am not sure if this is a bug or not.  In getLemmas(String word, String tag) method of JWNLDictionary, if you are looking up adjectives it checks if the tag starts with "J" or "a".  Anyone know if this a bug or deliberate?  (JWNL-1.3.3 distributed with opennlp-1.5.3)

      if (tag.startsWith("N") || tag.startsWith("n")) {
        pos = POS.NOUN;
      }
      else if (tag.startsWith("V") || tag.startsWith("v")) {
        pos = POS.VERB;
      }
      else if (tag.startsWith("J") || tag.startsWith("a")) {
        pos = POS.ADJECTIVE;
      }
      else if (tag.startsWith("R") || tag.startsWith("r")) {
        pos = POS.ADVERB;
      }
      else {
        pos = POS.NOUN;
      }

That make sense.  
Thank you.

Most likely not. It looks like the first option refers to PennTreeBank tags
(nouns - N-N, N-NS, etc, verbs - V-B, V-BD, etc, adjectives - J-J, J-JR,
J-JS, adverbs - R-B, etc) and the second option refers to WordNet "nvar"
tags - n-oun, v-erb, a-djective, adve-r-b. It's a bit strange to see two
type of tags together, but it does not seem too random :) This line from
"main" confirms the first guess:

dict.getLemmas(word,"NN")
