Component inherited type with EntityQueryDesc.Any doesn't work correctly

Hi, I found that Component inherted type (non struct type) with EntityQueryDesc.Any does not work correctly.

Here is minimul reproducible code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;
using System;
using Unity.Collections;

public class MyTestSystem : ComponentSystem
{
    EntityQuery query;

    protected override void OnCreateManager()
    {
        this.query = this.GetEntityQuery(new EntityQueryDesc()
        {
            All = Array.Empty<ComponentType>(),
            Any = new ComponentType[]{ typeof(MyTypeA), typeof(MyTypeB)},
            None = Array.Empty<ComponentType>(),
        });

        Entity e0 = this.EntityManager.CreateEntity();
        this.EntityManager.AddComponentObject(e0, new MyTypeA());

        Entity e1 = this.EntityManager.CreateEntity();
        this.EntityManager.AddComponentObject(e1, new MyTypeB());
    }

    protected override void OnUpdate()
    {
        var typeA = this.GetArchetypeChunkComponentType<MyTypeA>();
        var chunks = this.query.CreateArchetypeChunkArray(Allocator.TempJob);

        foreach(ArchetypeChunk chunk in chunks)
        {
            var objects = chunk.GetComponentObjects(typeA, this.EntityManager);

            // You can't use chunk.Has(typeA) because T is not IComponentData struct!
          
            for(int i = 0; i < objects.Length; i++)
            {
                Debug.Log($"Length : {objects.Length}");
                var obj = objects[i]; // This makes out of range exception
                Debug.Log("TypeA");
            }
        }

        chunks.Dispose();
    }
}

public class MyTypeA : Component
{
}

public class MyTypeB : Component
{
}

This issue is already sent as case 1143042, but I wrote this post to gather more information for this issue.

Thanks.

(Tested on Entites 0.0.12-preview.31 + Unity 2019.2.0b1)

YEP looks like its always returning length 0 for me

Thanks for testing this issue. I received the response from Unity:

So we can’t use “Any” filter for that. (But seems that “All” filter works correctly.)
