+Summary: ConstructorInfo.Invoke incorrectly throws System.MethodAccessException: Cannot invoke constructor of an abstract class.
+
+On Mono 1.2.3.1 the following code incorrectly throws an exception:
+
+using System;
+using System.Reflection;
+
+abstract class Base
+{
+}
+
+class Program : Base
+{
+	public static void Main(string[] args)
+	{
+		object obj = 
+System.Runtime.Serialization.FormatterServices.GetUninitializedObject
+(typeof(Program));
+		typeof(Base).GetConstructor(BindingFlags.Instance | 
+BindingFlags.NonPublic, null, Type.EmptyTypes, null).Invoke(obj, new 
+object[0]);
+	}
+}
+
+Actual result:
+Unhandled Exception: System.Reflection.TargetInvocationException: 
+Exception has been thrown by the target of an invocation. ---> 
+System.MethodAccessException: Cannot invoke constructor of an abstract 
+class.
+
+Expected result:
+no exception (it is legal to call the constructor on an abstract type, if 
+the instance passed in a non-abstract subtype).
