The problematic file.
Java command executed:

While reading a Excel file, I'm getting the following exception:
Exception in thread "main" java.io.IOException: Invalid header signature; read

The test.xls file is attached. The file was received from a Govt organization
and there is no way to verify which version of M$ Excel they use. The file
opens fine in Excel and openOffice.
