hg: jdk7/tl/jdk: 2 new changesets

[Ulf Zibis]

Alan,

why don't you take? :

public int hashCode() {
int h = hash;
if (h == 0) {
-            int off = offset;
- char val[] = value;
- int len = count; - -            for (int i = 0; i < len; i++) { 
-               h = 31*h + val[off++]; -           } -            hash = h;

+ int len = count; + if (len != 0) { +                char[] val = 
value; +                int i = offset; +                for (len += i; 
i != len; i++) +                    h = 31 * h + val[i]; 
+                hash = h; +            } } return h;
