Description

I'm trying to run ASM_4005 using the JVM XML processing, i.e. no Woodstox. I get the following error

SEVERE: XMLStreamException occured due to :

{0}

org.apache.tuscany.sca.contribution.processor.ContributionReadException: javax.xml.stream.XMLStreamException: ParseError
at [row,col]:[5,227]
Message: Attribute "xmlns" was already specified for element "zdef940251576:value".

The policy processing writes out the composite so it can be read back into a DOM to have XQuery applied. It's on the read that the error occurs. The XML that gets written is as follows....

Note that the lines marked ** does have xmlns="" xmlns="" which is what's causing the reader to fail.

Having looked at this there is some rather strange code in the org.apache.tuscany.sca.contribution.processor.BaseStAXArtifactProcessor.XAttr nested class. If no namespace URI is provided when writing an attribute then null is chosen.

public XAttr(String name, String value)

{ this(null, name, value); }

This is despite the class defaulting the uri meber variable to SCA11_NS

Anyone know why this is defaulted to null?
