+Summary: String.Join throws exception when any element in the parameter array is null
+
+Description of Problem:
+The static method Join of the class String fails when an array passed as 
+the second parameter contains at least one null value.
+
+Steps to reproduce the problem:
+Compile and run the following program:
+
+using System;
+namespace Test {
+	public class TestJoin {
+		public static void Main(string[] args) {
+			string[] array = new string[] {"hello ", null, "world!"};
+			Console.WriteLine(String.Join(String.Empty, array));
+		}
+	}
+}
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: A null value was found 
+where an object instance was required
+
+Expected Results:
+hello world!
+
+How often does this happen? 
+Always
