NullReferenceException is thrown when setting ParticleSystemJobData size through IParticleSystemJob
How to reproduce:
1. Open attached project "TestUnity.zip" and scene "ParticleSystemJob_setSize"
2. Enter Play mode
3. Observe Console window
Expected result: no errors are thrown, particle size is set to Vector2.one
Actual result: "NullReferenceException: Object reference not set to an instance of an object" is thrown
Reproducible with: 2019.3.0f1, 2020.1.0a15
Could not test with: 2017.4, 2018.4, 2019.2 (IJobParticleSystem interface is not detected, errors are thrown)

Resolution Note:
With the supplied particle system, the size is uniform, therefore we only store a single value per-particle (it would be a waste of memory to store the y and z values).
Therefore, your script should only set the sizes.x property.
To set a different value for each axis of the particle system (non-uniform) enable the 3D Start Size checkbox in the main particle system settings.
public void Execute(ParticleSystemJobData jobData)
{
var sizes = jobData.sizes.x;
for (int i = 0; i < jobData.count; i++)
{
sizes[i] = 1.0f;
}
}
