You can change your url to "coap://localhost/mqtt?c=client1", and set the uri_path option of "topic1/topic2" separately by the method "addUriPath", then the uri_path won't be split by "/". For example, you can make your put like,
String resourcePath = "topic1/topic2";
String uri = "coap://localhost/mqtt?c=client1”;
Request request = Request.newPut();
request.setURI(uri);
request.getOptions().addUriPath(resourcePath);

Hope it will help you.
