The upstream work on this issue is still in progress as fixes up to now have improved but neither eradicated the problem nor even diagnosed root cause - in fact the fixes actually stumbled into a secondary issue on Windows. So, I have been hesitating before pushing something that might not remove or workaround the problem.
It looks like Chris Plummer has identified the source of the Windows issue and provided a workaround for it (see https://bugs.openjdk.org/browse/JDK-8292879 and associated PR https://github.com/openjdk/jdk/pull/10519). So, I think it is probably worth proceeding with all the fixes up to and including this one.
