I am confused.
class Test<T extends String & @IntersectionType.TypeUse(value = 2)
How do I apply an annotation on the intersection type itself instead of on
individual bounds ? The code I sent earlier doesn't print the annotation
which might be the bug you are mentioning. It prints the intersection type
