Comment End of the Word in Paragraph using Java | Add Comment in Word Document

Dear Team,

i am getting array index out of bounds exception while insert comment for the end of the word in the paragraph . I am trying to insert comments based on the word position.

My code

public static void commentRangeOfRuns(Paragraph para,HashMap<String, String>position) {

	Document doc = (Document) para.getDocument();
	DocumentBuilder builder=new DocumentBuilder(doc);
	Node[] runs = para.getChildNodes(21, true).toArray();
	for(Map.Entry<String, String> entry:position.entrySet()) {
		String commentText=entry.getKey();
		String []positionary=entry.getValue().split("_");
		int start=Integer.valueOf(positionary[0]);
		int end=Integer.valueOf(positionary[1]);
		for(int i=start;i<end;i++) {
		Comment comment = new Comment((DocumentBase) doc, "comment", "LE", new Date());
		comment.getParagraphs().add((Node) new Paragraph((DocumentBase) doc));
		comment.getFirstParagraph().getRuns().add((Node) new Run((DocumentBase) doc, commentText));
		CommentRangeStart commentRangeStart = new CommentRangeStart((DocumentBase) doc, comment.getId());
		CommentRangeEnd commentRangeEnd = new CommentRangeEnd((DocumentBase) doc, comment.getId());
		runs[start - 0].getParentNode().insertBefore((Node) commentRangeStart, runs[start - 0]);
		runs[end - 0].getParentNode().insertBefore((Node) commentRangeEnd, runs[end - 0]);
		commentRangeEnd.getParentNode().insertAfter((Node) comment, (Node) commentRangeEnd);

Thanks in advance
