Jukka Zitting resolved TIKA-665.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.0
Assignee: Jukka Zitting
Fixed in revision 1126568.
The getAddress() call on a HyperLinkRecord was returning null for some link
within the spreadsheet, so I simply added a check for that. Not sure if this is
something that can/should be fixed in POI or if it's OK for the return value to
be null.
Note that there seems to be some extra debug output coming to System.out from
within POI when I parse this file. It would be nice if that could be avoided.

> Looking at the excel parser code, it seems that we're not doing anything
> wrong, so I think the issue is with the SAX stuff used by the CLI
