Hi Stefan,
It looks good to me.
Thanks for reviewing.
Sorry, I was on the meeting, wrote this email and forgot to push 'send'
button.
Just now discovered that it has not been really sent. :(
No problem. I pushed this yesterday to make the JDK 14 fork cut-off.
Thanks,
StefanK
Thanks,
Serguei

In the interest to get this integrated before the RDP cut-off I'm
going to push this ASAP. This has gone through tier1-tier3 testing.

Hi all,
Please review this patch to fix a problem with unintialized values in
our generation counters.
https://cr.openjdk.java.net/~stefank/8226797/webrev.01/
https://bugs.openjdk.java.net/browse/JDK-8226797
The jstat values NGCMN and OGCMN both return uninitialized values.
I stumbled upon this while creating a patch to remove the
GenerationSpec class.
GenerationSpec::_min_size is never initialized, and then used to
create the generations:
case Generation::DefNew:
return new DefNewGeneration(rs, _init_size, _min_size,
_max_size);
case Generation::MarkSweepCompact:
return new TenuredGeneration(rs, _init_size, _min_size,
_max_size, remset);
That in turn uses it to initialize the perf counters:
DefNewGeneration::DefNewGeneration(ReservedSpace rs,
size_t initial_size,
size_t min_size,
size_t max_size,
const char* policy)
...
_gen_counters = new GenerationCounters("new", 0, 3,
min_size, max_size, &_virtual_space);
I'm setting the value to _init_size, because it reflects how
MinNewSize and MinOldSize relates to NewSize and OldSize.
Thanks,
StefanK
