> 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}
