> Follow up from GROOVY-6408, GROOVY-7106, GROOVY-7274, GROOVY-7468, GROOVY-8909, GROOVY-8961, GROOVY-9734, GROOVY-9844, GROOVY-9915
> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> Map<String, Object> m(Date date, String query, String source)
> {
>   return [date: date, query: query, source: source]
> }
> {code}
> STC emits error "Incompatible generic argument types. Cannot assign java.util.LinkedHashMap<java.lang.String, java.io.Serializable<? extends java.io.Serializable<java.util.Date>>> to: java.util.Map<java.lang.String, java.lang.Object>".  It should be subject to same result type inference of assignment.
