Bug 30772

I've tried to read in a very large XLS file with 10 sheets and with a big bunch 
of data on every sheet. When creating the HSSFWorkbook object for that file I 
get an ArrayIndexOutOfBounds exception (code below).

java.lang.reflect.InvocationTargetException: java.lang.

Exception in thread "main" 

The code I used was:

POIFSFileSystem fs = new POIFSFileSystem( new FileInputStream(args[0] ) );	
HSSFWorkbook wb = new HSSFWorkbook( fs ); // Exception here!!!

To confirm that bug I tried a smaller XLS file and it worked fine. Maybe it's
because of the heavy use of 'short' symbols in POI.
