>                 URL:
>             Project: Lucene - Java
>          Issue Type: Bug
>    Affects Versions: 2.3.1

>            Assignee: Michael McCandless
>             Fix For: 2.4
> We've just found an insidious memory leak in our own application as we did not always
call Deflater.end() and Inflater.end(). As documented here;
> The non-heap memory that the native zlib code uses is not freed in a timely manner.
> FieldsWriter appears safe as no exception can be thrown between the Deflater's creation
and end() as it uses a ByteArrayOutputStream
> FieldsReader, however, is not safe. In the event of a DataFormatException the call to
end() will not occur.
