Nullable annotation on type parameter used in method vararg argument not recognized #1199
Description
In latest Guava 33.4.8 Sets.newHashSet the parameter elements are of @Nullable type, but NullAway fails to recognize it.
@SuppressWarnings("NonApiType") // acts as a direct substitute for a constructor call
public static <E extends @Nullable Object> HashSet<E> newHashSet(E... elements) {
HashSet<E> set = newHashSetWithExpectedSize(elements.length);
Collections.addAll(set, elements);
return set;
}Error:
/var/home/user/workspace/nullaway-test/WebsiteProvider.java:50: error: [NullAway] passing @Nullable parameter 'website' where @NonNull is required
final Set<String> params = Sets.newHashSet(website, company);

This got flagged only after recently bumping NullAway and Guava versions. It used to work before.
