Hi all,
Have you checked changes for this issue?
http://cr.openjdk.java.net/~ysuenaga/JDK-8163581/webrev.01/hotspot/
http://cr.openjdk.java.net/~ysuenaga/JDK-8163581/webrev.01/jdk/
For example, ParallelScavengeHeap.java overrides printOn() method.
This method shows addresses of each memory regions.
My proposal shows memory region of G1CollectedHeap and region size.
Please review and sponsor for it. If it is not enough, please tell me.
Thanks,
Yasumasa

Thank you for this fix, Yasumasa. This issue was manifested through the
'universe' command in clhsdb also, and your change fixes that. It would be
great if you could modify BasicLauncherTest.java to have some testing done for
this also.
Thank you,

G1CollectedHeap
Hi Yasumasa,
Adding in GC folk.
I agree with the need to override the printOn method, but can't comment
on the details of what you are actually printing.
Thanks,

Hi all,
When I chose "Heap Parameters" menu in HSDB, I got following value:
--------------------
Heap Parameters:
unknown subtype of CollectedHeap @ 0x00007f4d4c030510
(0x00000006c6e00000,0x00000007c0000000)
--------------------
I think it should not be "unknown subtype".
This value is shown by sun.jvm.hotspot.gc.shared.CollectedHeap#printOn().
This method is overrided in ParallelScavengeHeap and GenCollectedHeap.
However, G1CollectedHeap does not override.
I think G1CollectedHeap should override this method.
I uploaded a webrev for this issue.
Could you review it?

I'm jdk 9 committer, but I cannot access JPRT.
So I need a sponsor.
Thanks,
