I discussed with Dan offline to follow up my question in what cases javac should emit `(LFoo;)LR;` vs `(QFoo;)LR;`.   For the lambda case, having the receiver type as `QFoo;` is a good thing to do as it's an instance method of the enclosing class. 

For a method reference `o::m` where `o` is of primitive reference type, the factory type would be `(LFoo;)LR;`.   I have a test case that verifies the emitted code is:

28: invokedynamic #38,  0             // InvokeDynamic #1:get:(LX;)Ljava/util/function/Supplier;
