Here is an update on the method handle cracking API.
Though we will probably make some small adjustments, it appears to be
converging.

Key points:
- interface MethodHandleInfo (MHI
sensitive tokens like MH
objects, then perhaps MHI.asMember should not wrap the call to
InfoFromMemberName.reflectMember() in a PrivilegedAction...

Thanks for looking at that, Peter. You are right. The asMember call needs more
checks and less trust.

Just for my learning, what is the use model for this form of method
handle inspection?
Is there some cool technique that this facilitates?

yes,
if you crack a method handle, you get the reference to a method (the
constructor etc.)
so you can by

Yes. A bootstrap method receives 3 required arguments, a Lookup,

Simple example: Suppose you have a tree of GWTs that a clever
implementation compiles into a big hunk of bytecode
Actually that would be my dream, that hotspot is clever and I can just
let it do the work. Is it?

I would have thought one of the most common uses of breaking down a method
handle like this would be to immediately turn it into a java.lang.reflect
object and maybe examine annotations or exception information. So although
I don't think it should extend Member I do think it should have a standard

Duncan suggested:
return the parts that remain (both method handles and bound objects) as I
would guess that would be enough for debugging purposes and resource leak
hunting.
I think that if I could just get a collection of the bound objects in the
chain that
would be enough to do what I want
