ExceptionMapper, sendo interrompido um NullPointer de Crud

[robsonximenes]

Pessoal, criei um exceptionMapper, para minha exceção (herda RuntimeException); nela eu seto o status code e coloco um entidade simples. package br.gov.serpro.smartcert.exception;

import javax.ws.rs.core.Response; import javax.ws.rs.ext.ExceptionMapper; import javax.ws.rs.ext.Provider;

@Provider public class SmartCertExceptionMapper implements ExceptionMapper {

@Override
public Response toResponse(SmartCertException exception) {        
    int status = exception.getStatus();
    ErrorMsg entity = new ErrorMsg();
    entity.msg= exception.getMsg();
    entity.debbug= (exception.getMessage()!=null)?exception.getMessage():"";   
    return Response.status(status).entity(entity).type("application/json").build();
}    
public final class ErrorMsg{
    public String msg = "";
    public String debbug = "";
}  

} Ai quando rodo a aplicacao e lanco a excecao no BC. Sobe este erro no jboss:

O prblema é em CrudFilter

` @Override public void filter(ContainerRequestContext req, ContainerResponseContext response) throws IOException {

    if (response.getEntity() instanceof Result) {

        buildHeaders(response);

        response.setEntity(buildContentBody(response));

        if (!paginationHelper.isPartialContentResponse()) {
            response.setStatus(Status.OK.getStatusCode());
        } 
        else {
            response.setStatus(Status.PARTIAL_CONTENT.getStatusCode());
        }
    } 
    else {
        if (Status.BAD_REQUEST.getStatusCode() == response.getStatus() && drc.getEntityClass() == null) {
            paginationHelper.buildAcceptRangeWithResponse(response);
        }
    }

}

`

Ele esta interferindo no meu sistema. O crud pode ser desabilitado? Não deveria estar no core do projeto.

Todo codigo 400 que eu tentar lançar cai ai... estou usando 401 temporariamente para fugir deste problema

[robsonximenes]

Outra coisa, minha aplicacao é REST o crud é apenas no BC e DAO... Não é interessante ter u filtro na ponta

@robsonximenes você esta usando no seu pom.xml o parent do demoiselle?

Caso não queira usar o demoiselle-crud você pode deixar de usar o parent do demoiselle e importar os artefatos do demoiselle específicos para seu projeto.

Ex:

<dependency>
    <groupId>org.demoiselle.jee</groupId>
    <artifactId>demoiselle-core</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
     <groupId>org.demoiselle.jee</groupId>
     <artifactId>demoiselle-security-jwt</artifactId>
    <version>3.0.0</version>
</dependency>
