Typechecking of generics just broke (or something)

We get the following error:

/Users/bard/x10/x10-trunk/x10.dist/lib/x10.jar:x10/util/ArrayList.x10:223: Method or static constructor not found for cmp(T, T)
/Users/bard/x10/x10-trunk/x10.dist/lib/x10.jar:x10/util/ArrayList.x10:224: Method or static constructor not found for cmp(T, T)

From the library file ArrayList.x10:

 private def qsort(a: GrowableRail[T]!, lo: int, hi: int, cmp: (T,T)=>Int) {
        if (hi <= lo) return;
        var l: int = lo - 1;
        var h: int = hi;
        while (true) {
            while (cmp(a(++l), a(hi))<0);
            while (cmp(a(hi), a(--h))<0 && h>lo);
            if (l >= h) break;
            exch(a, l, h);
        }
        exch(a, l, hi);
        qsort(a, lo, l-1, cmp);
        qsort(a, l+1, hi, cmp);
    }

When trying to compile the test case examples/Constructs/Closures/ClosureConstraint1.x10.

(Actually, we get a whole pile of errors; that's just the first one. The rest are:
