Would you be ok to log a follow on task/bug if you feel coverage of this corner case is warranted ? Thanks.

I think this could be rolled under this https://bugs.openjdk.org/browse/JDK-8361344. So I'm not sure it needs a separate ticket. 

If there is not easy way of covering it here, I think this could be addressed in JDK-8361344
