26 * @summary Testing CDS (class data sharing) using varying object alignment. | |
27 * Using different object alignment for each dump/load pair. | |
28 * This is a negative test; using object alignment for loading that | |
29 * is different from object alignment for creating a CDS file | |
30 * should fail when loading. | |
