[Jobs][Editor] "readonly" modifier on a Native Collection inside Jobs causes a misleading Exception message

--

-

To reproduce:

1. Download attached project "SkinRaycast.zip" and open in Unity
2. Open "Demo" scene
3. Enter Play mode
4. Observe that in Console there will be spammed lots of misleading exceptions:

"InvalidOperationException: The native container has been declared as [WriteOnly] in the job, but you are reading from it."

5. Open Assets/SkinRaycasts/Jobs/RaycastJob.cs and remove "readonly" modifier (not the attribute) from line 13
6. Enter Play mode
7. Observe that no Exception is printed in Console

Notes:
- This issue appears on Windows and OSX
- In Standalone it seems that everything works fine

Reproduced on Unity 2018.2.10f1, 2018.3.0b4 and 2019.1.0a2
Could not check for regression on Unity 2018.1 because the whole project becomes corrupted

  1. Resolution Note (fix version 2018.3):

    Fixed in 2020.1.0a3
