Tim Allison created TIKA-1487:
---------------------------------
Summary: Add mime for pre-OLE2 xls file
Key: TIKA-1487
URL: https://issues.apache.org/jira/browse/TIKA-1487
Project: Tika
Issue Type: Improvement
Reporter: Tim Allison
Priority: Trivial
On the govdocs1 corpus, nearly 91% of xls exceptions have this stacktrace:
{noformat}
Caused by: java.io.IOException: Invalid header signature; read
0x0010000000060409, expected 0xE11AB1A1E011CFD0 - Your file appears not to be a
valid OLE2 document at

Excel is able to open the few files that I tried, and it looks like Excel
thinks these are version 4.
On the POI user list, [~gagravarr] identified this header as pre-OLE2 and asked
that we add the mime to Tika so that we can handle appropriately. Test file
soon to be attached.
