aoqi@0 | 30 | * When G1 ergonomically picks a maximum heap size it must be aligned to the region size. |
aoqi@0 | 31 | * This test tries to get the VM to pick a small and unaligned heap size (by using MaxRAM=555) and a |
aoqi@0 | 32 | * large region size (by using -XX:G1HeapRegionSize=32m). This will fail without the fix for 8013791. |
