> As described in [1] IndexWriter retains references to Reader used in Fields and that
can lead to big memory leaks when using tika's ParsingReaders (as those can take 1MB per ParsingReader).

> [2] shows a screenshot of the reference chain to the Reader from the IndexWriter taken
with Eclipse MAT (Memory Analysis Tool) . The chain is the following:
> IndexWriter -> DocumentsWriter -> DocumentsWriterThreadState -> DocFieldProcessorPerThread
 -> DocFieldProcessorPerField -> Fieldable -> Field (fieldsData)
