Switch from POIFSFileSystem to NPOIFSFileSystem, for speed and memory
improvements
----------------------------------------------------------------------------------
Key: TIKA-622
URL: https://issues.apache.org/jira/browse/TIKA-622
Project: Tika
Issue Type: Improvement
Components: parser
Reporter: Nick Burch
Assignee: Nick Burch
Priority: Minor
With POI 3.8 beta 1, there's an alternate OLE2 implementation NPOIFSFileSystem.
From an API level, it's very similar to the existing POIFSFileSystem class, but
internally it's lower memory and generally faster.
While NPOIFSFileSystem is currently read only (the write support has a couple
of gaps), for Tika's needs that isn't an issue
We should therefore switch our uses of POIFSFileSystem to NPOIFSFileSystem to
reduce memory and enhance speed.
