      Description

      Today ZGC reserves a huge chunk of virtual address space when the JVM starts. This typically succeeds because we grab the VA before anyone else has time to do so. But if some ASLR library or something was to grab a tiny part of the desired VA, ZGC can't start. We should support discontiguous heap reservations to support this.
