>
> When parsing a very large number of documents, which include a lot of eml
> files we see that
> The static field XMLReaderUtils.SAX_PARSERS is holding a massive amount of
> memory: 3.28 GB. This is a static pool of cached SAXParser instances, each of
> which is holding onto substantial amounts of memory, apparently in the
> fDocumentHandler field.
> This is a big data test we run regularly, the memory issues did not occur in
> Tika version 2.x
>
> I have attached JVM monitor screenshots.
