JDBC driver DatabaseMetadata getting DECIMAL_DIGITS causes java.lang.IndexOutOfBoundsException

[mainstreet439]

Attempting to iterate the Resultset returned by DatabaseMetadata.getColumns for a table with a DECIMAL, NUMERIC column etc. will result in a run time exception for column index 9 (DECIMAL_DIGITS).

ResultSet columns = dbMeta.getColumns( null, null, "TDEC", "%");
printRs("getColumns",  columns, columns.getMetaData().getColumnCount());

private void printRs(String header, ResultSet rs, int cols) throws SQLException{
    System.out.println(header);
    if (rs == null) {
        System.out.println("ResultSet was null");
    }
    long rows = 0;
    while (rs.next()) {
        for (int i = 1; i <= cols; ++i){
            System.out.print( rs.getObject(i));
            if (i < cols) {
                System.out.print(",");
            }
        }
        ++rows;
        System.out.println();
    }
    System.out.println("Rows printed " + rows);
}

create table if not exists TDEC ( RNUM integer not null , CDEC decimal(7, 2 ) );
