Memory Leak with the simplest Job test ! Bug !?

Hi i wanted to try implement some job based methods in a system and i decided to first give it a try.
The first job i created i get the errors in the image. It seems to work based on the time it takes not sure if it's giving correct results. However i am wondering why are these warning showing and how bad are they.

Here is super simple job. Am i doing something wrong !?

Using Unity 2018.3.11f1
EDIT : also using latest jobs, burst etc packages

Code (CSharp):

1.  
2. using UnityEngine;
3. using Unity.Jobs;
4. using Unity.Burst;
5. using Unity.Mathematics;
6.  
7. public class MT_Test : MonoBehaviour
8. {
9.     [BurstCompile]
10.     struct Test_01_Job : IJob
11.     {
12.         public int iters;
13.         public int vecsCount;
14.  
15.         public void Execute()
16.         {
17.             for (int j = 0; j < iters; j++)
18.             {
19.                 for (int i = 0; i < vecsCount; i++)
20.                 {
21.                     math.cross(new float3(1.0f), new float3(1.0f));
22.                 }
23.             }
24.         }
25.     }
26.  
27.     [SerializeField] int iterations = 100;
28.     [SerializeField] int vecsCount = 1000000;
29.  
30.     /// <summary>
31.     ///
32.     /// </summary>
33.     void Update()
34.     {
35.         if(Input.GetMouseButtonDown(0))
36.         {
37.             float t = Time.realtimeSinceStartup;
38.             Test_01_MT();
39.             Debug.Log(Time.realtimeSinceStartup - t);
40.         }
41.     }
42.  
43.     void Test_01_MT()
44.     {
45.         Debug.Log("Test 01 MT");
46.  
47.         Test_01_Job job = new Test_01_Job
48.         {
49.             iters = iterations,
50.             vecsCount = vecsCount
51.         };
52.         JobHandle handle = new JobHandle();
53.         job.Schedule(handle);
54.         handle.Complete();
55.     }
56. }
57.  
58.  

 

Code (CSharp):

1.         JobHandle handle = new JobHandle();
2.         job.Schedule(handle);
3.         handle.Complete();

You're completing the wrong handle

It should just look like this

Code (CSharp):

1.         var handle = job.Schedule();
2.         handle.Complete();
