27 * @summary Make sure that G1 ergonomics pick a heap size that is aligned with the region size | |
28 * @run main/othervm -XX:+UseG1GC -XX:G1HeapRegionSize=32m -XX:MaxRAM=555m TestRegionAlignment | |
29 * | |
30 * When G1 ergonomically picks a maximum heap size it must be aligned to the region size. | |
31 * This test tries to get the VM to pick a small and unaligned heap size (by using MaxRAM=555) and a | |
32 * large region size (by using -XX:G1HeapRegionSize=32m). This will fail without the fix for 8013791. | |
