RFR [8u60]: 8081590: The CDS classlist needs to be updated for 8u60

[Claes Redestad]

Hi,

new refresh up:

http://cr.openjdk.java.net/~redestad/8081590/webrev.02/

The refresh was put on hold earlier due to an incoming startup 
optimization, which affected the classlist (mostly
order).

I've rerun relevant tests, verified -Xshare:dump doesn't log any 
warnings and checked that footprint and startup improve.

Thanks!
