> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Reporter: Davanum Srinivas
> Assigned To: Rich Scheuerle
>
> When the client gets back a response, it throws a "JAXBBlockImpl block object
> is already consumed" exception. Reason is in RPCLitMethodMarshaller aorund
> line 348, we use MethodMarshallerUtils.getReturnElement to get back the
> return string. but then line 368, we call MethodMarshallerUtils.getPDElements
> and try to unmarshal the other 2 holders. So we get an exception saying that
> the block is already consumed.
