----------------------------------------------------------------
Thanks, I'd rather avoid risking tweaking that code to support yet another
hierarchy right just a day or so before the release...
By the way, the question is, given this declaration, "E extends Throwable", why
selecting IllegalArgumentExceptionMapper is a mistake given that both
UnmappedRuntimeException and IllegalArgumentExceptionMapper extend Throwable ?

> Key: CXF-7473
> URL: https://issues.apache.org/jira/browse/CXF-7473
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.1.11, 3.1.12
> Reporter: Jocelyn Lepage
> Fix For: 3.1.13, 3.2.0
>
>
> CXF seems to select an incompatible ExceptionMapper when using class
> hierarchies.
> More precisely, if I define an abstract exception class like following:
> {code:java}
> @Provider
> public abstract class AbstractExceptionMapper<E extends Throwable> implements
> ExceptionMapper<E> {
> ...
> {code}
> Then I define a concrete one for IllegalArgumentExceptions:
> {code:java}
> public class IllegalArgumentExceptionMapper extends
> AbstractExceptionMapper<IllegalArgumentException> {
> ...
> {code}
> IllegalArgumentExceptionMapper will then be selected even for
> RuntimeException subtypes unrelated to IllegalArgumentExceptions.
> See minimal project showing the problem
> [here|https://github.com/jlepage-appdirect/cxf-exception-mapper-bug]
> Similar (if not same) problem seems to have been reported via CXF-6635, but I
> do see this with 3.1.11 and 3.1.12.
> Thx!
