Very cool. I can confirm that this change resolves the long-standing
issue with the standard heap size (a quarter of RAM) and
vm.overcommit_memory=2 mode. Previously, you could not start more than
3 VMs in parallel, and with the change, that limitation is lifted.
Any chance we can backport this change to hs24 and jdk7u?
