HTTP Response splitting in case of java

Question

Is HTTP Response splitting possible in below case:

String requestFilename = request.getParameter("name");

response.addHeader("content-disposition", "attachment; filename=" + requestFilename);

I am directly appending the unsanitized request parameter to the reponse header.

My Question is that by using CRLF characters can we insert our own header into response.

So far i have tried \r\n and %0D%0A but they do not work.

Is response.addHeader() immune to such attacks?
Can someone explain it to me how this attack can be executed?
