100218: BigInteger staticRandom field

[Paul Ciprich]

All,

I've created a bug report to address a scalability problem with
BigInteger's staticRandom field. The problem is that the shared
staticRandom field causes bottlenecks with parallel code. The proposed
solution is to change the staticRandom field to a ThreadLocal and eliminate
the bottleneck by giving each thread its own copy of the SecureRandom
object. Bug 100218 contains a patch with the proposed change if it is
deemed acceptable.

Thanks,
