Subject [jira] [Commented] (CXF-5348) Exception mappers implementing ExceptionMapper through an abstract class are not mapped to the declared exception
Date Thu, 06 Aug 2015 09:08:05 GMT

    [ https://issues.apache.org/jira/browse/CXF-5348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14659714#comment-14659714
] 

Tim Gates commented on CXF-5348:
--------------------------------

I'm using 3.1.2 (for which this bug is mostly fixed), but it seems that a custom WebApplicationException
mapper which extends an abstract superclass will not be preferred over the default one. If
my custom mapper implements ExceptionMapper<WebApplicationException>, then all is fine.

> If we consider the following exception mapper, all Throwables will be mapped instead
of only the SomeClientExceptions :
> {code}
> @Provider
> public class SomeClientExceptionMapper extends AbstractBadRequestExceptionMapper<SomeClientException>
{}
> abstract class AbstractBadRequestExceptionMapper<T extends Throwable> implements
ExceptionMapper<T> {
>     @Override
>     public Response toResponse(T exception) {
>         return Response.status(Status.BAD_REQUEST).entity(exception.getMessage()).build();
>     }
> }
> {code}
> Please find attached, a sample project with some ITs showing the problem.
