I'm pushing method handles changes to JDK7 these days. Here's the
first:
http://hg.openjdk.java.net/jdk7/hotspot-comp/hotspot/rev/56aae7be60d4
The next one is imminent; see review request below. This one
refactors interface dispatching, so I don't need to write yet another
copy of the same assembly code for method handles.
The following one will refactor the assembly code generation of
subtype checking logic (used in checkcast, instanceof, aastore,
Class.isInstance, etc.). If you want to follow this activity, you may
want to lurk on hotspot-compiler-...@openjdk.java.net (CC-ed).
Both of the latter changes should help with interface injection
prototyping. (Hi, Tobias :-)

Subject: for review (M): 6812831 factor megamorphic invokeinterface
(for 6655638)
In response to a review request (thanks, Vladimir!) I've split the
refactoring of the itable lookup logic into a separate change request.
Here it is; please (re-)review:
http://cr.openjdk.java.net/~jrose/6812831/webrev
It is a little different from the corresponding changes in the mega-
review.
I cleaned it up slightly, so that the interface search loop is
tighter. (Should fit on an I$ line now.)
I also make it work on x86 (32 and 64) and SPARC.
