For 64 bit VM the default heap size is set to 1/4 of available physical memory. With memory > 120Gb the default heap size would be set to about 30Gb when compressed oops are used. It is fine for regular compressed oops but a little big for zero based compressed oops since lower part of virtual memory is used by os.
