 * @summary Test multiple nested multi-catch blocks with Exception hierarchies

 * @run main Pos11

 */

/*

 * For this test, exception hierarchy used:

 *

 *           Throwable

 *             /   \

 *      Exception  Error

 *       |    |      |

 *       A    B      D

 *            |

 *            C

 *            |

 *            E

 * As an exception is thrown within a nested try-catch block, outer catch blocks

 * will catch an exception or its child exceptions, so the same exception can

 * be caught and rethrown multiple times.
