Alessio Soldano updated JBWS-2686:
----------------------------------

    Fix Version/s:     (was: jbossws-native-3.2.0)


I've tested and committed the workaround, thanks Darran.

Unscheduling this while waiting for Sun to apply you patch. Then we'll remove the workaround.

> If a message received suffers an error converting a value the error is silently dropped and the field is left initialised with the default value.
> i.e. if an NumberFormatExceptions are thrown converting Strings to longs then the NumberFormatException is dropped and the field left to the default value.
> The Unmarshaller should by default terminate for the first error or fatal error, currently it only terminates for a fatal error: -

> This is a JAXB issue as raised here: -
>   https://jaxb.dev.java.net/issues/show_bug.cgi?id=655
> A workaround could be to add a ValidationEventHandler with this behaviour to our JAXBDeserializer: -
>          Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
>          unmarshaller.setAttachmentUnmarshaller( new AttachmentUnmarshallerImpl());
>          unmarshaller.setEventHandler(new ValidationEventHandler() {
>             public boolean handleEvent(final ValidationEvent event)
>             {
>                int severity = event.getSeverity();
>                return (severity != ValidationEvent.FATAL_ERROR && severity != ValidationEvent.ERROR);
>             }
>          });
>          
>          JAXBElement jbe = unmarshaller.unmarshal(xmlFragment, javaType);
>          value = jbe.getValue();
