Should this code above consider the VerifySilently flag?<br>
</blockquote>
<br>
Yes, it can. But I am afraid since this is a backport of the fix
that has been integrated into jdk9 it would have to be done as a
separate change.<br>
</blockquote>
<br>
Since the reason to add the VerifySilently is that it exits in
jdk8 and not in jdk9,<br>
</blockquote>
<br>
Oh yes, Unified GC logging removed it in 9.<br>

think you can integrate it in the same patch. If you're not
comfortable with <br>
that, it's fine to add the change separately.<br>

<br>
I will add the check for VerifySilently in this patch itself.<br>

Yes, the output with VerifyRememberedSets will be different
from the output with VerifyBeforeGC and VerifyAfterGC flags.
Since VerifyRememberedSets is not dependent on
VerifyBeforeGC and VerifyAfterGC options, it will be used
independently when we don't want to verify everything.<br>
<br>
Thanks,<br>
