Default methods for jdk8: request for code review

[Keith McGuigan]

Hello,

I'd like any review of the code which implements default methods in the 
JVM.  This is destined for jdk8 as part of JSR 335 (Lambdas), and 
tracked by CR 7200776.

The design and implementation is described in this short document:
http://cr.openjdk.java.net/~kamg/default_methods_in_hotspot.txt

And the code is here:
http://cr.openjdk.java.net/~kamg/default_methods/

Any review (even partial) would be appreciated.  Thanks!
