@ExE-Boss This patch intentionally does not support the said case. Reason being
that an instance method will require a hidden class receiver, yet this receiver
cannot be represented as part of a method type from the constant pool; so even
if you grab the MH from condy, you still cannot `invokeExact` in bytecode, but
have to perform an `asType` conversion first (or just use plain `invoke`)
