Thanks for catching this @mrserb and the patch itself looks like a clean backout to me.

However, I suggest we do this on https://github.com/openjdk/jdk8u for an interim 8u345 release.  I've just requested that version from ops and will update the jcheck rules on 8u when that is created.

Presumably we'll do the test under a different bug?
