Description

Since NiFi 1.23.0, it seems like comments are no longer supported in Jolt Spec (JoltTransformJson/JoltTransformRecord processors)

This however seems something that was already supported at least the most wide spread jolt engine https://jolt-demo.appspot.com/#inception

Reproducer :
We can easily reproduce it by simply putting a jolt with a comment using either JoltTransformRecord or JoltTransformJson processors as both are impacted.
