Marshalling to file results in com.sun.istack.internal.SAXException2

[stefanthaler]

When I try to marshall a policy to a file I get a SAXException2 (see below.)

// read
InputStream policyIS;
PolicyUnmarshaller reader =
new XacmlPolicyUnmarshaller( FunctionProviderBuilder.builder().defaultFunctions().build(),
DecisionCombiningAlgorithmProviderBuilder.builder().withDefaultAlgorithms().create() );
CompositeDecisionRule compositeDecisionRule = reader.unmarshal( policyIS );

// write
PolicyMarshaller writer = new Xacml30PolicyMarshaller();
FileOutputStream policyOutstream = new FileOutputStream( new File( "policyout.xml" ) );
writer.marshal( compositeDecisionRule, policyOutstream ); // <=exception thrown here

Caused by: com.sun.istack.internal.SAXException2: Instance of "javax.xml.bind.JAXBElement" is substituting "java.lang.Object", but "javax.xml.bind.JAXBElement" is bound to an anonymous type.

Can you attach the initial policy that you read into policyIS input stream?

I just copied this one.
