What is the correct way to configure custom mapper for WebApplicationException?

I've created class that implements implements ExceptionMapper<WebApplicationException> and registered it by environment.addProvider(new WebApplicationExceptionMapper());. My custom mapper works but only for some exceptions extended from WebApplicationException. For example it doesn't work for ConflictException and it also doesn't work for my custom exceptions with following constructor:

public ConflictException(URI location, Object entity) {
    super(Response.status(Response.Status.CONFLICT).location(location).entity(entity).build());
}

It will work if I'll remove super(Response.status..... This is very strange and I can't explain this. I'm not sure is it Jersey or Dropwizard behaviour.

What is correct way to configure mapper for all WebApplicationException and subclasses? Can you explain problems that I have?

May be a little too late, but found this to work.

for dropwizard 0.8 and above


in the yaml configuration

server:
    registerDefaultExceptionMappers: false

This would disable the DWs default exception mapper, then add your own exception mappers

// Register the custom ExceptionMapper(s)
    environment.jersey().register(new RestErrorsHandler());

This post shows how to create custom ExceptionMappers:

Perhaps this post could also help, if you having problems with your custom exceptionMappers: http://thoughtspark.org/2013/02/25/dropwizard-and-jersey-exceptionmappers/
