EmptyParser Singleton should be final
-------------------------------------
Key: TIKA-838
URL: https://issues.apache.org/jira/browse/TIKA-838
Project: Tika
Issue Type: Sub-task
Components: general
Reporter: Fabian Lange
Currently the Singleton EmptyParser is not a robust singleton. Other Code could
possibly exchange it, as it is not marked final.
This might pose a security risk.
Additionally, because the value is not final, the JVM cannot optimize it.
Attached patch adds the final attribute.
