[8u] RFR: 8217766: Container Support doesn't work for some Join Controllers combinations

[Severin Gehwolf]

Hi!

Could I please get a review for this 8u backport of 8217766. I see
Oracle backported it too to 8u281. The JDK 11 patch does not apply
cleanly, because a) no unified logging in hotspot in 8u b) split of jdk
and hotspot repositories in 8u.

I've manually backported hotspot changes. The JDK changes actually
applied cleanly. While this fixes part of the problem. JDK-8254854 will
be fixed separately and as a follow-up.

Bug: https://bugs.openjdk.java.net/browse/JDK-8217766
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8217766/01/

Testing: Manually on affected system with join controllers[1].
Container tests on Linux x86_64: no regressions.

Thoughts?

Thanks,
Severin
