Custom Task setTaskState Error example

I'm trying to set error messages for my custom tasks when some unexpected error occurs.   From the vSphere 5.5 docs, I understand I need to invoke Task.setTaskState with the following parameters:


    _this    ManagedObjectReference    // reference to task


    state    TaskInfoState    // must be TaskInfoState.ERROR for errors


    result   xsd:anyType      // valid only if TaskInfo.State.success SKIP


    fault     MethodFault     //  must directly or indirectly extend VimFault


 


In the Eclipse IDE, the method VimPortType.setTaskState says the final argument is of type LocalizedMethodFault, not MethodFault.   So, I created a LocalizedMethodFault variable and set its properties.  One property setter is setFault, which takes a MethodFault.  I know VimFault extends MethodFault, so I create a VimFault instance and use with setFault. 


However, I see VimFault has a setter setFaultCause, which takes an argument of, LocalizedMethodFault.   So this fault assignment is starting to get recursive.


                LocalizedMethodFault fault = new LocalizedMethodFault();
                VimFault vimFault = new VimFault();


            
                fault.setDynamicType("Runtime Error");
                fault.setLocalizedMessage(message);
                fault.setFault(vimFault);


                vimFault.setDynamicType("Runtime Error");
                vimFault.setFaultCause(fault);


In any case, I tried to use this code but it did not work.  Any ideas or example code that works would be greatly appreciated.
