In BoundedConcurrentHashMap.containsValue(), there are three assignments whose left-side variable isn't accessed at all: 1) int sum = 0; 2) int c = segments[i].count; 3) int c = segments[i].count; (same with 2 but in a different place) The first one is apparently safe to remove but I'm not sure about the others. Is there any reason to retain them, or can we remove them simply? -- Trustin Lee - http://gleamynode.net/
