Description

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
