That just notes the max amount of memory used, but not the actual memory it needs. If Java has memory available it makes sense that it uses it instead of spending time cleaning up unused objects.
In addition I have a feeling that these benchmarks are comparing short lived processes. Java does take a bit longer than some other languages to start unless you use native. But that doesn't matter much when you are running long lived services.
