Description

The documentation on customizing the exception mapping in JAX-RS mentions that custom mappers will be preferred over the default WebApplicationExceptionMapper:

Note that the custom WebApplicationException mapper, if registered, will be preferred to the default one.

See https://cxf.apache.org/docs/jax-rs-basics.html#JAX-RSBasics-CustomizingdefaultWebApplicationExceptionmapper

Lately I noticed that after upgrading CXF this is not true anymore for exception mappers that handle all kind of exceptions like ExceptionMapper<Throwable>.

In CXF-6568 it is mentioned that a new property (actual property name seems to be default.wae.mapper.least.specific) was introduced to restore the previous behavior. I think this property should be mentioned on the JAX-RS basics page, as I didn't find any other resource pointing to this possibility.
