The sample code + spreadsheet work OK in the latest svn trunk.

POIDocument.java must have changed since 3.0.2.  Line 74 does not seem to
correspond to the supplied stack trace.

If you find the same problem on the latest trunk, please re-open this bug.

Additional information:
- The test data is saved with a Debian OpenOffice.org 2.0.4.9 from Debian 
- If the test data is opened with OO.o 2.2.1 for Windows and resaved, POI can
open it

Is it just a broken file that OO.o can cope with for some reason? Even in that
case ClassCastException is a bit rough :)
