[classlib][math]exception compatibility: new BigInteger(Integer.MAX_VALUE, (Random)null)
----------------------------------------------------------------------------------------

                 Key: HARMONY-1047
                 URL: http://issues.apache.org/jira/browse/HARMONY-1047
             Project: Harmony
          Issue Type: Bug
          Components: Non-bug differences from RI
            Reporter: Denis Kishenko


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
	<no stack trace available>
