RFR: 4837946 - Faster multiplication and exponentiation of large integers

[Sergey Kuksenko]

Hi Brian,

In the parallel thread I see a new implementation of CRC32 & Adler32. I 
don't mean new HW intrinsics, I mean parallel operation using 
ForkJoinPool. I think BigInteger operations may be a better candidate 
for such kind of parallelization. For example Karatsuba may be 
forkjoined naturally.
