---------------------------------

             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 org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:140) at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:115) at org.apache.poi.poifs.filesystem.NPOIFSFileSystem.<init>(NPOIFSFileSystem.java:198) at org.apache.poi.poifs.filesystem.NPOIFSFileSystem.<init>(NPOIFSFileSystem.java:184) at org.apache.tika.parser.microsoft.OfficeParser.parse(OfficeParser.java:162) at org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:242) ... 13 more
{noformat}

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.
