Request body injected in bean annotated with @BeanParam

I want to inject the request body into a bean that is used as a BeanParam in a rest service.

This would be possible, according to https://stackoverflow.com/questions/33373668/inject-securitycontext-info-and-request-body-into-beanparam.

Unfortunately this doesn't work (tested with versions 2.25.1, 2.26).
