HSSFWorkbook throws Exceptions

           Summary: HSSFWorkbook throws Exceptions
           Product: POI
           Version: 1.5.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: HSSF

I wrote a following code to read xls file that is created by
Japanese MS-Excel 2000.

public class Test {
  public static void main ( String[] args ) 
                throws IOException {
    if ( args.length != 1 ) {
      System.err.println ( "Usage: java Test xls_file" );
      System.exit ( 0 );
    }
    FileInputStream fi = new FileInputStream ( args[1] );
    HSSFWorkbook wb = new HSSFWorkbook ( fi );
    fi.close ( );
  }
}

It's almost O.K.
But, reading some xls file, HSSFWorkbook throws following exceptions.

1) Exception in thread "main" java.lang.NullPointerException
