Error getting Workorder collections to client device in SAP WM 6.2

All,

We are upgrading from Agentry to SMP 3.0, also SAP WM 5.2 to SAP WM 6.2. We are reusing all the java objects with changes inline to 6.2 OOB. We are getting the details in Fetch BAPI for WorkOrders Headers and WorkOrders collections, but when passing the same to Agentry Objects we are getting below error

4 (Windows Structured Exception), EXCEPTION_ACCESS_VIOLATION (EXCEPTION_ACCESS_VIOLATION, 0000000035B93D29, 0, R, 0000000000000068, ), agent\userFetchConnectionSet.cpp#236:class JavaBackEndUserFetchConnection |

Do we have any document to follow/refer in knowing the necessary changes to be done in Java layer and SAP Config panel.

An immediate solution/ guidance would be much helpful.

Thanks.
