That's awesome! I would love to see some bench-tests to see how much it
improves performance. I've been coding quite a bit of Java recently and
have grown to like it.

High Level Summary for Garbage Collection:
Guarded Storage Facility (GSF)
Also known as less-pausing garbage collection, Guarded Storage Facility is a new
architecture introduced with z14 to enable enterprise scale Java applications
to run without
periodic pause for garbage collection on larger heaps.
z/OS
GSF support allows an area of storage to be identified such that an Exit
routine gets control if
a reference is made to that storage. GSF is managed by new instructions that
define Guarded
Storage Controls and system code to maintain that control information across
un-dispatch
and re-dispatch. Enabling a less-pausing approach improves Java garbage
collection.
Function is provided on z14 running z/OS 2.2 and later with APAR OA51643
installed.
MACHMIG statement in LOADxx of SYS1.PARMLIB provides ability to disable the
function.
