+Summary: Invoking an static method fails with the JIT
+
+Description of Problem:
+I call GetValue (null, null) on a PropertyInfo. The property is static.
+It does not work with mono and works with mint
+
+
+Steps to reproduce the problem:
+1. compile whis program referencing System.Drawing and run
+using System;
+using System.Drawing;
+using System.Reflection;
+
+public class MyClass
+{
+ public static void Main (string [] args)
+ {
+ Type t = typeof (Color);
+ PropertyInfo [] props = t.GetProperties ();
+ foreach (PropertyInfo prop in props){
+ if (prop.Name == "Red"){
+ Console.WriteLine ("{0}", prop.GetValue
+(null, null));
+ break;
+ }
+ }
+ }
+}
+
+
+Actual Results:
+(process:1516): ** WARNING **: unhandled exception
+System.NullReferenceException: "A null value was found wher
+e an object instance was required"
+in <0x00062> (runtime invoke wrapper) .MyClass:Main (object,intptr,intptr)
+
+Expected Results:
+Color [Red]
+(though there is a bug in the library that makes it output [255,255,0,0]
