Probes are not working as intended

The way ProbeTransform was implemted suggests it should be only instantiated once for a transformer because it stores information which should change over time.
ProbeTransform is however not used as a singleton bean, but a new instance is created for every ready/live check. This totally contradicts the way ProbeTransform is implemented. I am pretty sure ProbeTransform should be a singleton bean (and only initialized once).
