Mocking Log4Net Bug

There are problems with mocking Log4Net. Here's the production code:

    public class Log4NetTest
    {

        public void TestRun()
        {
            log4net.Config.XmlConfigurator.Configure();
            var log = LogManager.GetLogger(typeof(Log4NetTest));
            log.Error("Worse");
            log.Info("Dont Kid");
        }
    }

    public class Log4NetTypeMock
    {
        public static readonly ILog log
            = LogManager.GetLogger(typeof(Log4NetTypeMock))
            ;

        public static readonly Log4NetTest log4Net;
    }

Now run test two tests:

  
        [Test, Isolated]
        public void Test2()
        {
            Isolate.WhenCalled(() => Log4NetTypeMock.log4Net)
            .ReturnRecursiveFake();
            Assert.AreEqual(2, 1 + 1);
        }

The test passes, fine.

But now uncomment this line

  = LogManager.GetLogger(typeof(Log4NetTypeMock))

Run the Test2() again, this time, it fails!
