that would be incompatible with native annotations!

> Currently, {{AnnotationLiteral.hashCode()}} always returns {{0}} if there are no members (ignoring annotation type completely). Although it does not break {{Object.hashCode()}} contract, I believe we should either return a number based on the annotation type (to make the annotation literal instances more usable in hash tables) or simply return zero and don't cache the value at all.
