             Summary: CXF not (always) responding with the correct exception when working with an exception hierarchy
                 Key: CXF-4940
                 URL: https://issues.apache.org/jira/browse/CXF-4940
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.7.4
            Reporter: David G
            Priority: Minor


Hi there,

For a webservice I'm currently building (java first), I have a few custom exceptions arranged in a hierarchy. In order to have them properly declared in the WSDL, I list all possible exceptions in the WebMethod declarations, not only the top ones. That is, if exceptions B->A, I declare :
@WebMethod
String helloWorld() throws A,B;

And it works, as far as the WSDL is concerned.
What doesn't work is that when requesting the service and raising a 'B' (child) exception, the response embeds an 'A' (parent) fault.


I seem to have narrowed down the culprit to org.apache.cxf.interceptor.FaultOutInterceptor.getFaultForClass(BindingOperationInfo,Class<?>), which stops at the first exception 'assignable to' the one actually raised. I 'patched' it locally to return the 'closest to the one raised', and it does the trick for me.

I hope an actual CXF contributor can take a look at this issue. I'm a beginner with CXF, and I might use it improperly. Please bear with me if that's the case :)
