24 Apr 2001, eval1127@eng -- 1.3.x/1.4.x significantly slower
than 1.2.x. See Comments section.
----------
java version "1.3.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)
Java HotSpot(TM) Client VM (build 1.3.0_02, mixed mode)

Sample program:

import java.math.*;

public class powtest
{
    public static void main(String[] args)
    {
        long t1 = System.currentTimeMillis();

        BigInteger result = BigInteger.valueOf(10).pow(65536);

        System.out.println("runtime: " +
           (System.currentTimeMillis()-t1)/1000.0 + " secs");
    }
}

System is: W2K Server SP1 AMD 550MHz

Running against JDK 1.3.0_02 it takes about 65 seconds. If running against JDK
1.2.2_006 it takes 0.5 seconds. Someone seems to have badly "over-optimized"
this ...
