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