HTMLEditorKit.Parser.parse() method is not giving a proper HTMLDocument alw

Question

Hi,
I am developing util program for HTML filter, for my project. I have find using HTMLDocument we can do that.
But when I created I found few starnge things.
HTMLEditorKit.Parser.parse() method is not giving a proper HTMLDocument always. the below application will show the HTML one if you comment the String str ="" ; and uncomment the next line.
I am wondering why this happens.
import java.io.StringReader;
import java.io.StringWriter;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.HTMLWriter;
import javax.swing.text.html.parser.ParserDelegator;
public class HTMLDocExample {
public static void main(String args[]) throws Exception {
System.out.println("start the parsing");
String data = "dsfdssfsdf<A HREF='http://yahoo.com'>HTMLEditorKit.Parser</A><h1>dsfdsf</h1><table border='1' class='test'><tr><td><input type='text'>dfsf</input><select id='id1' name='name1'><option>fff</option><option>aaaaa</option></select><input type='text'/><a href=#></a></td></tr></table>";
String str ="" ;
//String str ="<TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE><TABLE >test</TABLE>" ;
StringReader br = new StringReader(data + str );
HTMLEditorKit htmlKit = new HTMLEditorKit();
HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument();
HTMLEditorKit.Parser parser = new ParserDelegator();
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0);
parser.parse(br, callback, true);
StringWriter writer = new StringWriter();
HTMLWriter hWriter = new HTMLWriter(writer, htmlDoc);
hWriter.write();
String outPut = writer.toString();
System.out.println(outPut);
System.exit(0);
}
