Null Pointer Exception in clone method of TermVectorsReader class!

Hello everybody,

I got the null pointer exception in the method clone of the
TermVectorsReader class. Exactly in the given statement:    
clone.tvx = (IndexInput) tvx.clone();

This happens when trying to indexing.

I think that is due to the constructor of that class. 

  TermVectorsReader(Directory d, String segment, FieldInfos fieldInfos)
    throws IOException {
    if (d.fileExists(segment + TermVectorsWriter.TVX_EXTENSION)) {
      tvx = d.openInput(segment + TermVectorsWriter.TVX_EXTENSION);
      checkValidFormat(tvx);
      tvd = d.openInput(segment + TermVectorsWriter.TVD_EXTENSION);
      tvdFormat = checkValidFormat(tvd);
      tvf = d.openInput(segment + TermVectorsWriter.TVF_EXTENSION);
      tvfFormat = checkValidFormat(tvf);
      size = (int) tvx.length() / 8;
    }
->    else {
->    	System.out.println("The file " + segment + " doesn't exist !");
->    }

    this.fieldInfos = fieldInfos;
  }
  
So my question: what happens when a segment doesn't exist!? I think that
the exception is due to this because tvx may be null in this case!

Thanks
Samir

Samir,

Can you reproduce this with the very latest Lucene from CVS?
If you can, could you write a little class that reproduces this
exception and stick it in Bugzilla, please?

I'm using Term Vectors on simpy.com, and I haven't had any issues with
them.

Thanks,
Otis
