Didn't see the need of a generic while answering the question.
I thought that you had to choose for linkedList because also an add-method was used. Thought that add only was available with list-interface implementations and not with queue.
So I did some checking and found that queue-implementations also have an add method.
Maybe nice to mention in the explanation.

Also the explanation is talking about getRequestForProcessing(). This has to be getRequestToProcess().

Fixed.
