• JSpecify mode: an inferred @Nullable type argument is lost in an array component and inside a wildcard bound of the call's result

• JSpecify mode: a List<T> whose T admits null reaches List.copyOf unreported when it passes through another generic call first

• JSpecify mode: a type variable whose bound admits null is accepted as the type argument of a type parameter that excludes null (NonNullParameter<T>, Class<T>, Test.<T>m())

• JSpecify mode: inference substitutes a synthetic @NonNull for an unconstrained type variable, so a List<T> with T extends @Nullable Object flows into a List<Object>
