Jaxb marshaller characterEscapeHandler

I have the following problem. I set the following properties for the marshaller:

marshaller.setProperty (Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.setProperty ("com.sun.xml.bind.characterEscapeHandler", new CharacterEscapeHandler () {
    public void escape (char [] ch, int start, int length, boolean isAttVal, Writer out) throws IOException {
        String s = new String (ch, start, length);
        System.out.println ("Inside CharacterEscapeHandler ...");
        out.write (StringEscapeUtils.escapeXml (StringEscapeUtils.unescapeXml (s)));
    }
});

When I try to redirect an object to SOAPBody with the following code:

SOAPMessage message = MessageFactory.newInstance (). CreateMessage ();
marshaller.marshal (request, message.getSOAPBody ());

CharacterEscapeHandler.escape is not called, and characters are not escaped, but this code:

StringWriter writer = new StringWriter ();
marshaller.marshal (request, writer);

calls CharacterEscapeHandler.escape (), and all characters are escaped ... This is the usual behavior for JAXB. And how can I avoid characters before placing them inside a SOAP body?

Update:

Our system must interact with another system that expects text to be escaped. Example for a message sent by another system:
