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

[Stuart Marks]

Hi, I'm finally getting back to this. Sorry for the delay.

I've written up a CSR for this. Can you review it please? When you've done so, 
please edit the CSR and add your OpenJDK user ID to the Reviewed By box (scroll 
most of the way to the bottom).

     https://bugs.openjdk.java.net/browse/JDK-8230331

I'm using this CSR to apply to both OpenJDK 11.0.x and Oracle JDK 11.0.x. The 
code change is the same and all the same issues apply. Note that this change is 
quite different from the JDK 13 change, so the CSR is quite different as well. 
I've included some background and the explanation I posted in this email thread 
earlier.

The webrev is unchanged from my posting a few weeks ago:

     http://cr.openjdk.java.net/~smarks/reviews/8227368.jdk11u/webrev.0/

(I haven't rebased it to the very latest jdk11u-dev; I suppose it might change 
somewhat, though I think it unlikely.)

Christoph, I'd appreciate it if you could run this change through SAP's test 
system. Please let me know about the results or any problems you encounter.

Thanks!

We definitely shouldn't differ at this place... And in that case I suppose you'd have had to file a CSR anyway since I understood Joe telling that Oracle 11u would use the CSR process.
