[11u]: RFR JDK-8227368: EnumSet.class serialization broken in JDK 9+

[Stuart Marks]

Hi, yes, I saw that Andrew Haley had approved this at the beginning of last 
week. Of course we were at JVMLS+OCW so no actual work got done on it. More 
recently I've been catching up and I've also been trying to test the change 
before pushing it. Unfortunately I've been in a bit of a wrestling match with 
our internal build/test system, since it's not set up to jdk11u-dev (it's only 
set up for the Oracle 11u family).

Is there a CI system for jdk11u-dev? Would that be shipilev's setup?

Re CSR, I guess I should have pushed the fix last week before the CSR was 
instituted for 11-updates. j/k :-)

Actually I did talk to Joe Darcy and we agreed that this would be a good test 
run for the CSR for updates, not only because the mainline fix had a CSR, but 
because the "backport" differs significantly from the mainline fix.

Relatedly, the backport CSR will be completely different from the CSR for the 
mainline fix. A different set of compatibility considerations is in play, 
specifically, no specification changes.

I was assuming that I'd work on this, but if somebody (Peter) wants to pick it 
up that'd be ok too.
