I meant it passes, while I tested it locally: TimSort: 264438688 ComparableTimSort: 226445108

I think it should work, it passed when running with a -Xmx around 950m.

[~ctornqvi], Test will pass after applying cleanup from JDK-8073354 ( changing -Xmx385m to -Xms385m ) : $ ~/Downloads/9b51/bin/java -XX:-UseCompressedOops -Xms385m -XX:+PrintFlagsFinal -d64 -Xmixed -server TimSortStackSize2 67108864 | grep -i 'maxheap\|compress\|sort' uintx CompressedClassSpaceSize = 1073741824 {product} uintx MaxHeapFreeRatio = 100 {manageable} uintx MaxHeapSize := 1010827264 {product} bool UseCompressedClassPointers = false {lp64_product} bool UseCompressedOops := false {lp64_product} TimSort: 264438688 ComparableTimSort: 226445108 Is relying on chosen by default ergonomic value of MaxHeapSize robust enough ?
