ExceptionMapper<WebApplicationException> is not working in DEV mode

When users define a list of custom exception mappers, it should be possible to match an incoming exception to one of the custom mapper.

The behavior should be the same in DEV, JVM and native modes.

For instance, when users define below list of custom exception mappers:

@Provider
public class CustomExceptionMapper1 implements ExceptionMapper<BadRequestException> {
    @Override
    public Response toResponse(BadRequestException t) {
        return ...
    }
}

@Provider
public class CustomExceptionMapper2 implements ExceptionMapper<Exception> {
    @Override
    public Response toResponse(Exception t) {
        return ...
    }
}

Then, generating a not found exception:

curl -X POST http://localhost:8080/hellow?myparam=value1

The expectation is that method CustomExceptionMapper2.toResponse should be called in DEV mode, JVM mode and native mode.
