DelegatingXMLStreamWriter.writeCData(text) writes several CDATA sections for a signed XML file

HI,

When implementing a CDATA interceptor in order to include a signed XML file in a SOAP envelope, we are getting several CDATA sections in the XML that makes the service reject the envelope:

import java.util.regex.Pattern;

import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;

import org.apache.cxf.staxutils.DelegatingXMLStreamWriter;
 
/**
 * Simple CDATA XML Stream Writer that exports some items as CDATA
 */
public class CDataXMLStreamWriter extends DelegatingXMLStreamWriter {
 
    private static final Pattern XML_CHARS = Pattern.compile( "[&<>]" );
    private static final String CDataOpen = "<![CDATA[";
    private static final String CDataClose = "]]>";
    
    public CDataXMLStreamWriter(XMLStreamWriter del) { 
    	super(del);
    } 

    @Override 
    public void writeCharacters(String text) throws XMLStreamException { 
    	boolean useCData = XML_CHARS.matcher( text ).find();

    	if (useCData) {
    		//super.writeCharacters(CDataOpen);
System.out.println("text" + text);    		
    		//super.writeCharacters(text);
    		//super.writeCharacters(CDataClose);
    		super.writeCData(text);
    	}else { 
    		super.writeCharacters(text); 
    	} 
    }
    
    public void writeStartElement(String local) throws XMLStreamException { 
    	super.writeStartElement(local); 
    } 
}

That's urgent to solve this for us.

This is an example of the unwanted output:
