The webrev is here :

As described in the CR evaluation and suggested fix, the speed-up on a
dedicated micro-benchmark
is more than x10 on either SPARC or x86 architectures. The footprint
cost is ~6kbytes from a static
char array constant data to collect digits from integer values.
There is an associated regression test, together with a
micro-benchmark that may be run optionally.
