> Different exception behaviour when create a huge BigInteger.
> Actually it's impossible to create BigInteger with numBits=Integer.MAX_VALUE, but RI throws an Exception while Harmony throws an Error.
> Test --------------------------------------------------------------
> mport java.math.BigInteger;
> import java.util.Random;
> public class bug9282 {
> public static void main(String args[] ) {
> new BigInteger(Integer.MAX_VALUE, (Random)null);
> }
> }
> Output -------------------------------------------------------
> RI
> java.lang.NegativeArraySizeException: Negative size-268435455
> at java.math.BigInteger.randomBits(BigInteger.java:471)
> at java.math.BigInteger.<init>(BigInteger.java:464)
> at bug9282.main(bug9282.java:6)
> Harmony
> java.lang.OutOfMemoryError
