------------------------------------
> Default WebApplicationExceptionMapper should be optionally made less specific

>
> Key: CXF-6568
> URL: https://issues.apache.org/jira/browse/CXF-6568
> Project: CXF
> Issue Type: Improvement
> Components: JAX-RS
> Reporter: Sergey Beryozkin
> Assignee: Sergey Beryozkin
> Priority: Minor
> Fix For: 3.1.3, 3.0.7
>
>
> Now that the default and custom providers are kept in a single
> ProviderFactory with a parent-child relationship the default
> WebApplicationExceptionMapper will win over custom providers which are less
> specific (ex, RuntimeException mappers) but which expect to catch
> WebApplicationException.
> It is been confirmed on the spec experts list that it is expected that custom
> mappers can catch WAE thrown by the runtime itself therefore the fact that
> CXF uses WAE to enforce spec-related error conditions is sound.
> There's no clarity though how the runtime is expected to manages such
> runtime-originated WAEs - via its own WAE mapper or even RuntimeException
> mapper or somehow else.
> Therefore a property "make.default.wae.least.specific" is introduced to
> ensure a CXF default WAE mapper is only used if no other custom mapper can
> handle a given WAE to minimize any portability concerns.
> This can be further addressed once we get more clarity on the issue
