> Key: CXF-6983
> URL: https://issues.apache.org/jira/browse/CXF-6983
> Project: CXF
> Issue Type: Improvement
> Components: JAX-RS
> Affects Versions: 3.1.6
> Environment: CXF 3.1.6 with JAXB annotated beans
> Reporter: Mike Golod
> Priority: Trivial
>
> When unmarshal json payload to JAXB annotated bean sometimes we can get an
> UnmarshallingException (e.g. for dates). That exception already contains very
> descriptive message. AbstractJAXBProvider#handleExceptionStart extracts it.
> Then in AbstractJAXBProvider#handleJAXBException:
> {code:title=AbstractJAXBProvider#handleJAXBException}
> if (linked != null && linked.getMessage() != null) {
> Throwable cause = linked;
> while (read && cause != null) {
> if (cause instanceof XMLStreamException &&
> cause.getMessage().startsWith("Maximum Number")) {
> throw ExceptionUtils.toWebApplicationException(null,
> JAXRSUtils.toResponse(413));
> }
> if (cause instanceof DepthExceededStaxException) {
> throw ExceptionUtils.toWebApplicationException(null,
> JAXRSUtils.toResponse(413));
> }
> cause = cause.getCause();
> }
> sb.append(linked.getMessage()).append(". "); // this causes the
> problem
> }
> {code}
> This code adds another message from linked exception. Message text is the
> same. Finally we get something like:
> {quote}
> JAXBException occured: <error text>. <error text>.
> {quote}
