 * @bug 8312434
 * @summary A jar file containing classes in the same package. Sign the jar file with
 *          a disabled algorithm. The jar will be treated as unsigned.
 *          Dump only one class into the CDS archive. During runtime, load the class
 *          stored in the archive and then load another class not from the archive
 *          but from the same pacakge. Loading of the second class should not result
 *          in sealing violation.
