  configured to limit entity expansion.

  NOTE: In Apache Tika 1.19 (CVE-2018-11761), added an entity expansion limit for XML parsing.
  However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers,
  as per the documentation, removes the user-specified SecurityManager and thus removes entity
  expansion limits after the first parse. Apache Tika 1.19 is therefore still vulnerable to entity
  expansions.");
