 * @test CdsDifferentObjectAlignment

 * @summary Testing CDS (class data sharing) using varying object alignment.

 *          Using different object alignment for each dump/load pair.

 *          This is a negative test; using  object alignment for loading that

 *          is different from object alignment for creating a CDS file

 *          should fail when loading.

 * @requires vm.cds

 * @requires vm.bits == 64
