+Summary: ThreadStateException handling during the finally clause
+
+Description of Problem:
+If a ThreadStateException is thrown, the finally clause is exceuted and 
+after that the exceptions is rethrown. If another exception is thrown, 
+this exception is thrown and can be caught.
+Then the Microsoft CLR continues the execution, while mono rethrows the 
+ThreadStateException.
+
+
+Steps to reproduce the problem:
+	class Class1
+	{
+		public static void bla()
+		{
+			try
+			{
+				Console.WriteLine("Thread started ... 
+waiting");
+				Thread.Sleep(10*1000);
+			}
+			catch( ThreadAbortException ) {}
+			finally
+			{
+				try
+				{
+					string blaa = null;
+					try
+					{
+						Console.WriteLine( 
+blaa.ToString() );
+					}
+					catch( Exception e ) { 
+Console.WriteLine( e.ToString() ); }
+					Console.WriteLine("The will apear 
+on ms CLR!");
+				}
+				catch( Exception e )
+				{
+					Console.WriteLine("\nThis 
+exception is not thrown on ms CLR:");
+					Console.WriteLine( e.ToString() );
+				}
+			}
+		}
+		[STAThread]
+		static void Main(string[] args)
+		{
+			Thread myThread = new Thread( new ThreadStart( 
+bla ) );
+			myThread.Start();
+			Thread.Sleep( 3000 );
+			Console.WriteLine("Aborting Thread");
+			myThread.Abort();
+			Console.WriteLine("Joining Thread");
+			myThread.Join();
+			Console.WriteLine("Done");
+			Console.ReadLine();
+		}
+	}
+
+Actual Results:
+Thread started ... waiting
+Aborting Thread
+Joining Thread
+System.NullReferenceException: A null value was found where an object 
+instance was required
+in [0x00020] (at /home/matthias/Development/mono/Class1.cs:25) 00 
+ThreadAbortTest.Class1:bla ()
+
+
+This exception is not thrown on ms CLR:
