Am getting a build failure:

src/share/classes/sun/invoke/util/ValueConversions.java:964: error:
   cannot infer type arguments for ClassValue;

private static final ClassValue<MethodHandle[]> TYPED_COLLECTORS = new ClassValue<>() {
                                                                                      ^
reason: cannot use '<>' with anonymous inner classes

details ...
