[classlib][math] compatibility: no NPE for java.math.BigDecimal((BigInteger) null)
----------------------------------------------------------------------------------

         Key: HARMONY-784
         URL: http://issues.apache.org/jira/browse/HARMONY-784
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Vladimir Ivanov


The Harmony method java.math.BigDecimal((BigInteger) null) doesn't throw NPE while RI do it.
Note1: NPE is thrown for java.math.BigDecimal((BigInteger) null).toString()
Note2: BEA and SUN have different behavior

=============== test.java ==========================
import java.math.*;

public class test {
	public static void main(String args[] ) {
                         	try {
			BigDecimal bd = new BigDecimal((BigInteger) null);
			if (bd != null)
				System.out.println("Failed1");
			else
				System.out.println("Failed2");
		} catch (NullPointerException e) {
			System.out.println("Passed");
			e.printStackTrace();
               }
        }
}
================================================
