[Lucene Bug] Did not decrement max count

[Fuxiang Chen]

Dear Lucene Developers,

In the source file "SolrXMLSerializer.java", there is a flaw in the code
fragment that is using transferTo.

Original Code
--------------------
      long size = fcin.size();
      long position = 0;
      while (position < size) {
        position += fcin.transferTo(position, MB32, fcout);
      }

The MB32 (which is the max count needs to be decrement.

See reference: http://stackoverflow.com/questions/7379469

Changed Code
----------------------
while (position < size) {
    long count = inChannel.transferTo(position, MB32, fcout);
    if (count > 0)
    {
        position += count;
        MB32 -= count;
    }
}


Please consider fixing this bug.

Thanks!
