> The BeanUtil.deserialize(Class, OMElement, ObjectSupplier, String) in Adb 
> module does not handle xsi:nil attributes on array elements properly.
> In the given example test case a 2D string array (that is part of a POJO) is 
> being sent to an Echo Java service.
> The 2D array contains an null array and a null array element:
> String[][] stringArray2D = new String[][] { new String[] { "axis2", null}, 
> null}
> The request is send using ADB client stub and it's OK:
> <ns2:echoSimplePOJO xmlns:ns2="http://test.tempuri.org";>
>     <ns2:simplePOJO>
>          <names xmlns="http://test.tempuri.org/xsd";>
>              <names>axis2</names>
>              <names xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
> xsi:nil="1" />
>           </names>
>           <ns1:names xmlns:ns1="http://test.tempuri.org/xsd"; 
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:nil="1" />
> </ns2:simplePOJO>
> The request, however, contains an empty string rather than a null string, and 
> does not contain the null array:
> <ns:return xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
> xmlns:ax23="http://test.tempuri.org/xsd"; xsi:type="ax23:SimplePOJO">
>     <ax23:names>
>          <ax23:names>axis2</ax23:names>
>          <ax23:names></ax23:names>
>     </ax23:names>
> </ns:return>
> The problem is that the deserialize(..) method does not check for xsi:nil.
> Additionally it does not put deserialized null array elements inside the 
> valueList, so they are effectively skipped.
