Description

The XMLStreamReaderInputStream created by the StaxConverter will fail if the document does not define a default namespace, a tag contains an attribute without namespace prefix and the XMLStreamWriter from the JDK is used.

The error message is:
javax.xml.stream.XMLStreamException: NamespaceURI cannot be null
at com.sun.xml.internal.stream.writers.XMLStreamWriterImpl.writeAttribute(XMLStreamWriterImpl.java:615)
at org.apache.camel.converter.jaxp.XMLStreamReaderInputStream.ensureBuffering(XMLStreamReaderInputStream.java:106)

The fix is relatively simple: a check needs to be introduced that replaces null namespaceUris with empty namespace Uris.

The issue was introduced with CAMEL-10070.

The issue will not happen with unit tests because those use the woodstox Stax parser.
