JDK 15 RFR of JDK 15 RFR: JDK-8225361 : Start of release updates for JDK 15

[Joe Darcy]

Hello,

Please review the VM portions of the start-of-release updates for JDK 15:

     http://cr.openjdk.java.net/~darcy/8225361.5/

Some additional adjustments to class file parsing for records may occur 
and get merged in before the start of 15.

Thanks,
