Saxon

An XSLT stylesheet has an error in it at some point.

The created Saxon transformer is called to transform over a custom SAXResult implementation.

When the transformation runs, it reports a different error than the one which exists in the XSLT styleshet:

The method "ResultDocument.processInstruction" has a finally clause which closes the receiver if an error occurs when transforming:

    try {

        out.startDocument(0);

        content.process(context);

        out.endDocument();

    } catch (XPathException err) {

        err.setXPathContext(context);

        err.maybeSetLocation(this);

        throw err;

    } finally {

        //RECEIVER CLOSE IS CALLED

        out.close();

    }

and in this case the ContentHandlerProxy.close() method delegates to the "handler.endDocument()" method which throws an exception because not all elements in the SAX handler have been closed. The elements have not been closed because of the original exception which is now masked by this IllegalStateException which jumps from the finally clause.
