This certainly looks like the right fix for the right 'known issue' i.e. 
the one reported in JDK-8168996. However, I don't really understand how 
you came to the conclusion that 8168996 was the issue that is causing 
the problem, given that the bug is private.

Are you basing that assumption on the brief description in the email 
thread? Or the fact that the fix makes the problem go away? Or both? Or 
maybe something else?

I would prefer simply to approve this patch but it would help to have 
more background if you have any.

regards,
