[Bug xml/28589] New: XSLT transform throws TransformerException with SAXSource

[dpirkle at symyx dot com]

Transforming a SAXSource to a DOMResult can fail if the SAXSource is
constructed from an InputStream.  This is because the resolveDOM() method of
gnu.xml.transform.XSLURIResolver ends up calling resolveURL() on the Source
that is passed to it, but a Source will not always resolve to a URL. 
StreamSources built on InputStreams do not trigger a call to resolveURL() and
are handled OK.

I've attached a source example that reproduces the exception, and a new version
of XSLURIResolver.java that fixes the problem.  The fix tries to extract an
InputStream from the SAXSource, and only goes on to attempt a resolution to a
URL if it can't get the InputStream directly.
