But not JDK head, to which the fix was applied?

OK, but (presumably) we'd still have to deal with the bug which was fixed
by JDK-8279219. In that case we'd need to do another fix, to back-port
JDK-8279219 properly. Or is it the case that the 8279219 is not important?

Roland Westrelin will be back in a few days' time, and he will be able
to analyse the problem.
