Axis 2 1.6.2. issues with nil="1" attribute in the request

Dear All.

Currenly i am using axis 2 1.4.1 for generating server side stubs

Now we are actually planning to migrate to axis 2 1.6.2

But the problem is

after generating the stubs, when i see the differenct between stubs of
axis 2 1.4.1 and axis 2 1.6.2 below condition is generated(in axis 2
1.6.2) as part of stub generation

 nillableValue =
reader.getAttributeValue("http://www.w3.org/2001/XMLSchema-instance","nil");
                                    if ("true".equals(nillableValue)
|| "1".equals(nillableValue)){
                                        throw new
org.apache.axis2.databinding.ADBException("The element:
"+"custShortName" +"  cannot be null");
                                    }

When i was tested, my request are failing because of this condtion
generating for all values in XSD with the below sample request

<urn1:bookName xsi:nil="1"/>(in Axis 2 1.6.2)
