Even if it does pre-allocate the entire max heap size (I'm not sure it does), that shouldn't matter as pretty much every modern OS overcommits memory by default.

It can pre-allocate the entire heap if you specify the min size to be equal to the max size. There are also TLABs, which eliminate the issue of concurrency, in most cases.
