JAXRSOutInterceptor throws NullPointerException for unknown requests when using
exception mapper
------------------------------------------------------------------------------------------------
Key: CXF-1858
URL: https://issues.apache.org/jira/browse/CXF-1858
Project: CXF
Issue Type: Bug
Components: REST
Affects Versions: 2.1.2
Environment: windows XP, jdk1.6.0_07, tomcat 6.0.18
Reporter: david
JAX-RS webservice
When a client requests URL that isnt a valid service endpoint and using an
Exeption mapper to return more detailed error, if you add an entity in the
response the JAXRSOutInterceptor throws a NPE.
java.lang.NullPointerException
at
org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor.processResponse(JAXRSOutInterceptor.java:150)
at
org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor.handleMessage(JAXRSOutInterceptor.java:61)
.....
The exception mapper:
public class MyExceptionMapper implements ExceptionMapper<Exception>
{
private static Logger LOG =
LogUtils.getL7dLogger(MyExceptionMapper.class);
@Override
public Response toResponse(Exception ex)
{
LOG.logp(Level.WARNING, "MyExceptionMapper",
"toResponse","Caught Exception:", ex);
return
Response.status(503).type("text/html").entity("Myexception error
description").build();
}
}
If I dont put the entity in the response it works, but with an entity in the
response it causes a NullPointerException.
currently in SVN and 2.1.2 JAXRSOutInterceptor.java line 150 is :
writer.writeTo(responseObj, targetType, invoked.getGenericReturnType(),
invoked != null ? invoked.getAnnotations() : new
Annotation[]{},
responseType,
response.getMetadata(),
out);
perhaps should be this :
writer.writeTo(responseObj, targetType,
invoked != null ? invoked.getGenericReturnType()
: null,
invoked != null ? invoked.getAnnotations() : new
Annotation[]{},
responseType,
response.getMetadata(),
out);
