Where to put @Nullable on methods with null return types?

Question

When used javax.annotation.Nullableto designate methods as "potentially returning a value null", where to put the annotation @Nullable? About a method or return type?

Is there any technical difference, or is it strictly a style problem?

Style A:

@Nullable
public Object blah() { ... }

Style B:

public @Nullable Object blah() { ... }
