Hi I am start to play around with lucene2.0 and this is the error that I am getting

>>> doc.add(Field("path", fin.getPath (), Field.Store.YES, Field.Index.UN_TOKENIZED))
Traceback (most recent call last):
  File "<input>", line 1, in ?
java.lang.IncompatibleClassChangeError: java.lang.IncompatibleClassChangeError: org.apache.lucene.document.Field and org.apache.lucene.document.Field$Store disagree on InnerClasses attribute

this is happaning with either jython2.1 or jython2.2.a, is anybody knows something about this
