Thomas Jodes commented on CAMEL-21129:
--------------------------------------
In my case (clientRequestValidation true and binding mode 'off' -> ['jackson'
here|https://github.com/apache/camel/blob/a2212f39466d7ef9185b6557f872ca9a8a7da3b8/core/camel-support/src/main/java/org/apache/camel/support/processor/RestBindingAdviceFactory.java#L64])
that leads to a NPE, will it be adressed in 4.8.0?
> NPE rooted in RestBindingAdviceFactory in camel-support after upgrade 4.6->4.7
