Error in xml write

There is a issue in StringSerializer.java.
The problem is when a parameter is an array of objects.
When a object of this array is a String, the xmlrpc does not insert the <string></string> tag.
The xmp-rpc specification says that the tag must be inserted !
I found the method where is the problem.

public void write(ContentHandler pHandler, Object pObject) throws SAXException

{ write(pHandler, null, pObject.toString()); }

I changed the null parameter to constant STRING_TAG and then the tag was inserted well.
Thanks.
