Subject [jira] Commented: (COCOON-2148) SourceProtocolHandler causes NPE
Date Mon, 26 Nov 2007 10:34:43 GMT

    [ https://issues.apache.org/jira/browse/COCOON-2148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12545394
] 

Andreas Hartmann commented on COCOON-2148:
------------------------------------------

The SVGSerializer fails with Batik 1.7 beta 1 because SAXDocumentFactory.startElement() now
contains a block which depends on the parser (which is not initialized and causes an NPE):


        if (inProlog) {
            inProlog = false;
            try {
                isStandalone = parser.getFeature
                    ("http://xml.org/sax/features/is-standalone");
            } catch (SAXNotRecognizedException ex) {
            }
            try {
                xmlVersion = (String) parser.getProperty
                    ("http://xml.org/sax/properties/document-xml-version");
            } catch (SAXNotRecognizedException ex) {
            }
        }

> I used an action to pass the current source resolver to the SourceProtocolHandler, but
this resulted in an NPE because the URI of the TranscoderInput object was null. After I applied
a little patch to the SourceProtocolHandler which enabled the fallback to the default handler
if the URL to resolve is null, it worked.
