ch.ethz.inf.vs.californium.coap.OptionSet
OptionSet is a collection of all options of a request or a response. OptionSet provides methods to add, remove and modify all options defined in the CoAP, blockwise CoAP, observing CoAP and supports arbitrary defined options.
Noteice that this class is not entirely thread-safe: hasObserve=> (int) getObserve()

          Request request = exchange.getRequest();
          int num = block2.getNum() + 1;
          int szx = block2.getSzx();
          boolean m = false;
          Request block = new Request(request.getCode());
          block.setOptions(new OptionSet(request.getOptions()));
          block.setDestination(request.getDestination());
          block.setDestinationPort(request.getDestinationPort());
          
          block.setType(request.getType()); // NON could make sense over SMS or similar transports
          block.getOptions().setBlock2(szx, m, num);
