> Key: FOP-2362
> URL: https://issues.apache.org/jira/browse/FOP-2362
> Project: Fop
> Issue Type: Bug
> Components: general
> Affects Versions: 1.1
> Environment: Apple OSX 10.9.2 / Java version 1.7.0_11
> Reporter: Hauke Haastert
> Attachments: extensions.diff, simple.xsl, test.fo

> When rendering an XSL-FO file that contains an AFP-Extension to the
> intermediate format while using Saxon as XSLT transformer, a
> NullPointerException is thrown.
> Steps to reproduce:
> 1. Download and unpack the FOP 1.1 binary release.
> 2. Change into the root directory "fop-1.1" of the release
> 3. Download Saxon HE from
> http://repo1.maven.org/maven2/net/sf/saxon/Saxon-HE/9.4/Saxon-HE-9.4.jar and
> copy the file to the lib directory of the FOP 1.1 release
> 4. Edit the file fop that is located in the root directory of the release and
> add the following JVM parameter to the java_exec_args:
>
> -Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl
> The line should now look like:
> java_exec_args="-Djava.awt.headless=true
> -Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl"
> 5. Download the attached files test.fo and simple.xsl and run the following
> fop command:
> fop -fo test.fo -out application/X-fop-intermediate-format test.if.xml
> Actual Results:
> Application throws NullPointerException:
> java.lang.NullPointerException
> at
> net.sf.saxon.event.ReceivingContentHandler.getNodeName(ReceivingContentHandler.java:391)
> at
> net.sf.saxon.event.ReceivingContentHandler.startElement(ReceivingContentHandler.java:316)
> at
> org.apache.fop.util.DelegatingContentHandler.startElement(DelegatingContentHandler.java:185)
> at
> org.apache.fop.render.afp.extensions.AFPPageSetup.toSAX(AFPPageSetup.java:125)
> at
> org.apache.fop.render.intermediate.IFSerializer.handleExtensionObject(IFSerializer.java:680)
> Expected Results:
> Application should render IF from FO
> Additional Information:
> In the toSAX method of the class
> org.apache.fop.render.afp.extensions.AFPPageSetup the method addAttribute of
> the class org.xml.sax.helpers.AttributesImpl is called with null as first
> argument. Due to the APIDOC of the class org.xml.sax.helpers.AttributesImpl
> the first argument must either be the namespace or an empty string, but not
> null:
> uri - The Namespace URI, or the empty string if none is available or
> Namespace processing is not being performed.
> When changing the parameter value to an empty string, no NullPointerException
> is thrown anymore. The same problem exists in other classes in the package
> org.apache.fop.render.afp.extensions, so I added a diff file for the complete
> package (extensions.diff).
> The exception is not thrown when using Xalan as XSL transformer.
