I'm trying to define some graphQL types dynamically using a typeDefinitionFactory and the fact that field values can be resolved using the Map.get() method. It seems to be working fine as long as I don't have fields with list types. Here's a minimal example of the problem I bumped into:

public static class MyFooType {
    public String bar;
}

public static class FooResolver extends HashMap<String, Object> implements GraphQLQueryResolver {
    @Override
    public Object get(Object key) {
        if ("foo".equals(key)) {
            return Arrays.asList(new MyFooType(), new MyFooType());
        }
        throw new IllegalArgumentException("unknown field " + key);
    }
}

public static void main(String[] args) {
    GraphQLSchema schema =
        SchemaParser.newParser().schemaString("""
                type Query{ foo: [FooType] }
                type FooType { bar: String }
                """)
            .resolvers(new FooResolver())
            .dictionary("FooType", MyFooType.class)
            .build().makeExecutableSchema();
    System.out.println("OK!");
}

This causes an exception:

Exception in thread "main" graphql.kickstart.tools.SchemaClassScannerError: Unable to match type definition (ListType{type=TypeName{name='FooType'}}) with java type (java.lang.Object): Java class is not a List or generic type information was lost: class java.lang.Object
	at graphql.kickstart.tools.TypeClassMatcher.error(TypeClassMatcher.kt:20)
	at graphql.kickstart.tools.TypeClassMatcher.match(TypeClassMatcher.kt:78)
	at graphql.kickstart.tools.TypeClassMatcher.match(TypeClassMatcher.kt:23)
	at graphql.kickstart.tools.SchemaClassScanner.scanResolverInfoForPotentialMatches(SchemaClassScanner.kt:257)
	...

I guess the problem could be that the framework doesn't know whether to expect a java.util.List or a java array as the foo value. Is there a way to pass this information?
I tried .dictionary("[FooType]", List.class), but that results in another exception:

Exception in thread "main" graphql.kickstart.tools.SchemaClassScannerError: Class in supplied dictionary 'java.util.List' specified type name '[FooType]', but a type definition with that name was not found!
