Regarding the LDC proposal, it came to my attention that JSR 294
(Modularity) is planning to add new ConstantPool types as well. This
makes me very opposed to the idea of trying to overload the existing
CONSTANT_* rather than adding CONSTANT_MethodHandleref_info and
CONSTANT_MethodTyperef_info.
That seems right. Let's talk about this at the Summit. The advantage
of using constants rather than reflective factory methods is the
ability of tools (or the JVM) to see ahead of time how the app. is
going to link itself. There may also be compactness benefits.
Knowing the method handle before runtime will allow, by example, to avoid
the method type check in case of MethodHandle.invoke().
