Requests Fail with ClassCastException on weblogic 10.3.5 when initiating approval request. solution apply patch

Requests Fail with ClassCastException
When you install Oracle Identity Manager on Weblogic Server (10.3.5.0), the request fails with the following exception:

Unable to instantiate the workflow process due to: Tasklist mapping failed for workflowdefinition: default/DefaultRequestApproval!1.0 due to oracle.bpel.services.workflow.query.ejb.TaskQueryService_oz1ipg_HomeImpl_1035_WLStub cannot be cast to oracle.bpel.services.workflow.query.ejb.TaskQueryServiceRemoteHome.

This happens when initiating the approvals for a request.

Workaround:
For Weblogic Server 10.3.5 you must download and install patch 12944361. Weblogic Server 10.3.6 do not require this patch
