Hi Mandy,
Just another observation of the code in InnerClassLambdaMetafactory...
For the useImplMethodHandle case you generate the protectedImplMethod
static field to hold the MH and a static setter method:
mv = cw.visitMethod(ACC_PRIVATE + ACC_STATIC,
"setImplMethod", DESCR_SET_IMPL_METHOD,
null, null);
...but then later after you define the class you inject the MH via a
"staticSetter" method handle:
MethodHandle mh =
lookup.findStaticSetter(lookup.lookupClass(), NAME_FIELD_IMPL_METHOD,
MethodHandle.class);
mh.invokeExact(implMethod);
So you don't invoke the generated setter method but set the field via
special kind of method handle (equivalent to putstatic bytecode).
You can remove the setImplMethod method generation code.
Good catch. Removed the unused method.
