But please note that test will run only if UseG1GC set. It will
be skipped otherwise (with no GC option set for example).<br>

Agreed.<br>

Could you please review changes for 8065749 ?<br>
Test TestG1HeapRegionSize.java is G1-specific and could

I think your suggested fix will work, but I have a question
regarding the original change.<br>
<br>
Before the original change the test explicitly checked that
it was run with G1 and just skipped otherwise:<br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/hs-gc/hotspot/comparison/6464714dd742/test/gc/arguments/TestG1HeapRegionSize.java">http://hg.openjdk.java.net/jdk9/hs-gc/hotspot/comparison/6464714dd742/test/gc/arguments/TestG1HeapRegionSize.java</a><br>
<br>
Was this test really failing at all? I thought we were only
going to add @requires to tests that were failing due to
conflicting GC combinations. If it was working before I
think a different approach to fix the current problem would
be to revert back to the old code without @requires.<br>
</blockquote>
<br>
You are right, it was our mistake. This test wasn't reverted
when we decided to update only failing tests.<br>
Yes, a possible solution would be just to roll back the
previous change, but I don't think it makes sense just to roll
back.<br>
<br>
What I suggest:<br>
1) keep this test G1 specific (@requires g1 and +UseG1
explicitly) - what is proposed by this change<br>
2) make tests GC independent - remove @requires and check in
tests that RegionSize == <expected> in case of G1, and
RegionSize == 0 in case of another GC.<br>
<br>
I don't think that original variant (silently pass if not g1)
is the right solution.<br>
</blockquote>
<br>
I don't think 2) makes sense. G1HeapRegionSize is not set to 0
for other collectors and there is really no reason to do that
either. So, testing the value of that with other GCs is just a
waste of time.<br>
<br>
Considering that, I don't really see why 1) is better than
reverting to the original code. After all, we are not sure how
we want @requires to work and in my mind it is better to use it
as little as possible until we have figured out how it should
work.<br>
<br>
Thanks,<br>
