Constraints for list not included in schema

[robp94]

If I have a class like this:

public class TestObject {
    private List<@Pattern(regexp = "^1") String> list;

    @Pattern(regexp = "^1")
    private String nonList;
    ...

I get a schema like this:

input TestObjectInput {
  list: [String]
  nonList: String @constraint(pattern : "^1")
}

For the type of the list, the constraint is not in the schema. Constraints for the list like max/min length do work.

I guess this is just another variation on #1366
We've made some progress in scanning generic types, but apparently there are still some gaps.

Most importantly, I think we do not yet support wrapper directives (and constraints directives via bean validation). I have started to work on the feature, but it will take some time to implement.

For #1366, the problem was that if the type argument contained @NonNull, every wrapper was non-null.
See:

Line 80 in ba3cf91

private static boolean markParameterizedTypeNonNull(Type fieldType, Type methodType) {

smallrye-graphql/server/implementation/src/main/java/io/smallrye/graphql/bootstrap/Bootstrap.java

Line 917 in ba3cf91

if (wrapper != null && wrapper.isCollectionOrArrayOrMap()) {

List<Set<Collection<@NonNull Integer>>> => [[[Int!]!]!]!
List<Set<@NonNull Collection<Integer>>> => [[[Int]]]
I might have fixed the issue locally, but I still need to test it...
