Non static bootstrap method

[John Rose]

This is worth a clarification:  The only meaningful bootstrap methods will be static methods and constructors for subclasses of CallSite.  I will add a note to the effect into the javadoc.

Using a virtual method of class C as a BSM means that you expect the first stacked argument to the BSM to be the receiver, of type C.  Unless you were to choose a virtual on MethodHandles.Lookup that will serve your purpose (and there is nothing that will return a CallSite), there's no way that any of the stacked arguments will act as the method's receiver.
