No.

It would defer JDK-8226575 (high prio) for JDK-8221710 (test-only, low
priority). Also, I'm not sure JDK-8221710 has other dependencies. This
fix should go in now and then we can amend JDK-8221710 later once it
goes in. The earlier we get it in the more testing it can get before
8u272 goes live. It already had to wait for JDK-8203357. Note that the
initial RFR of this got sent over a month ago. This all adds up.

Thanks,
