[pylucene-dev] memory leak passing sequence of string

[Aaron Lav]

I noticed this with StopFilter: there seems to be a missing
DeleteLocalRef in JArray's specialization for strings.  I'm attaching
a test case and a patch.  (The other specializations all look OK, since
they're scalar types not requiring allocation.)

    while 1:
        result = lucene.StandardTokenizer(reader)
        result = lucene.StopFilter(result, stop_set)
