Hi John. Updates on the prototype: I have had to put the development of the prototype on hold due to deadlines in the Jython project associated with PyCon. The status is that I have implemented injection for invokeinterface. There is still some testing to be done there and then I'll move on to the other injection points. But great to see that method handles are making their way into the official JDK7. /Tobias > > -- John > > Begin forwarded message: > > *From: *John Rose <john.r...@sun.com> > *Date: *March 5, 2009 5:54:04 PM PST > *To: *hotspot compiler <hotspot-compiler-...@openjdk.java.net> > *Subject: **for review (M): 6812831 factor megamorphic invokeinterface > (for 6655638)* > > In response to a review request (thanks, Vladimir!)
