Inconsistency using SUN Rowset Reference Implementation

Question

I am Using the RowSet reference implemention with Oracle Database.
I am having a class which takes a input in form of XML adhering to the webrowset format.
The xml contains some records to be inserted , some records to be updated and some records to be deleted.
This xml is then fed to a WebRowSet using the webRowSet.readXml method which takes a Reader as a parameter. I am using a StringReader here.
Here is the code snippet:-
public void executeUpdate(String webRowSetXML)throws SQLComponentException{
System.out.println(" webRowSetXML "+webRowSetXML);
StringReader sr = new StringReader(webRowSetXML);
WebRowSet webRowSet = null;
try {
webRowSet = new WebRowSetImpl();
webRowSet.readXml(sr);
webRowSet.acceptChanges(connection);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
I found here that the insertion and updating works without any problem , but the deletion doesn't work.
Then to study this problem , i wrote a program with two WebRowSets, one will be the producer of the data and the other will be the consumer.
the first WebRowSet will read the data from the data source , delete a record using the following piece of code:-
wrs1.absolute(6);
wrs1.deleteRow();
And then i generate a String XML using the writeXML method.
Then i feed this xml to the readXML method of the second WebRowSet and i call the acceptChanges method of the second WebRowSet. But the record doesn't get deleted.Also after printing the xml from the second WebRowSet , the <deleteRow> tag is absent from the xml.
The same condition works properly for the insert and update operation and the respective <insertRow> and <updateRow> methods appear in both the xml's generated from both the WebRowSet's.
Is this a bug in the webRowSet implemention or is it a problem of Oracle? Or is it that something else needs to be done for the delete operation to work.
I tried the same thing with Pervasive SQL instead of oracle. Here only the insert operation works.
Any body please help me in solving this problem...

From the sun desc above.
The RowSet interface is unique in that it is intended to be implemented using the rest of the JDBC API. In other words, a RowSet implementation
is a layer of software that executes "on top" of a JDBC driver.
Implementations of the RowSet interface can be provided by anyone,
including JDBC driver vendors who want to provide a RowSet
implementation as part of their JDBC products.
