>                 Key: LUCENE-1326
>                 URL: https://issues.apache.org/jira/browse/LUCENE-1326
>             Project: Lucene - Java
>          Issue Type: Bug
>    Affects Versions: 2.3.1
>            Reporter: Robert Newson
>            Assignee: Michael McCandless
>
> 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;
> http://bugs.sun.com/view_bug.do?bug_id=4797189
> 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.
