Isolator bug with Isolate.nonpublic.wascalled.witharguments

gistfile1.cs

from my tdd class:

 [TestFixture, Isolated]
    public class LoginManagerWithStaticTestIsolator1
    {
        [Test]
        public void IsLoginOK_LoggerThrowsException_CalledWebService()
        {
            LoginManagerWithFutureObject lm = new LoginManagerWithFutureObject();

            RealLogger fakeLogger = Isolate.Fake.Instance<RealLogger>();

            Isolate.WhenCalled(()=>fakeLogger.Write("")).WillThrow(new LoggerException("Stub Message"));
            Isolate.Swap.NextInstance<RealLogger>().With(fakeLogger);

            Isolate.WhenCalled(()=>Environment.MachineName).WillReturn("MachineName");

            //Isolate.NonPublic.WhenCalled(lm, "GetMachineName").DoInstead(context => "MachineName"); // Will work
                        
            lm.AddUser("user", "password");
            lm.IsLoginOK("user", "password");


            /// DOES NOT WORK
            Isolate.Verify.NonPublic.WasCalled(lm, "CallWebService").WithArguments("Stub Message MachineName");

            //Isolate.Verify.WasCalledWithExactArguments(() => lm.IsLoginOK("user", "password")); // Will work
        }
    }

using System;
using System.Collections;

namespace MyBillingProduct
{
	public class LoginManagerWithFutureObject
	{
	    private Hashtable m_users = new Hashtable();

	    public bool IsLoginOK(string user, string password)
	    {
	        try
	        {
	            new RealLogger().Write("blah");
	        }
	        catch (LoggerException e)
	        {
	            new WebService().Write(e.Message + Environment.MachineName);
	        }
	        if (m_users[user] != null &&
	            m_users[user] == password)

		{
			m_users[user]= newPassword;
		}
