Ortwin Glück commented on XMLCOMMONS-87:
----------------------------------------
Even the XMLStreamException from JDK-1.6 does that nowadays. I wonder why we
are stuck with this ancient copy in xml-apis.jar which has lower quality than
the JDK.
> XMLStreamException not calling "super(th)" in constructors
> ----------------------------------------------------------
>
> Key: XMLCOMMONS-87
> URL: https://issues.apache.org/jira/browse/XMLCOMMONS-87
> Project: XML Commons
> Issue Type: Bug
> Components: XML Commons External (StAX)
> Affects Versions: XML Commons External 1.4.01
> Reporter: Ortwin Glück
>
> The XMLStreamException in spec stax-api 1.2 is not calling the super(th) or
> super(msg, th) for the constructors that take a throwable. There are two
> problems this causes:
> 1) The "cause" is never set so the exception.getCause() always returns null
> and potentially important information in the cause is discarded.
> 2) For the super(th) one, no message is set at all. Thus, all information
> that could be useful is lost unless I specifically cast the exception to an
> XMLStreamException and call the getNestedException(). Any generic exception
> handling mechanism would not be able to provide a useful error message.
> see also GERONIMO-6509, apparently the fix has never been upstreamed.
