While working on the example [`transformer-demo`|[https://github.com/apache/camel-examples/tree/main/examples/transformer-demo],] I realized that it fails with the next error:

{code}
After a deeper investigation, it appears that it occurs because the datatype of the message is lost after been copied by the ProcessorValidator such that it ends up trying to convert a json payload with the JAXB fallback type converter which fails with the previous error.
