#317 Getting System.MissingMethodException on newer versions of ikvm

[Jens Villadsen]

Hi

I'm doing a Mono project on Mac and I've seem to hit a bug. It affects all version found on Nuget after v7.3.4830 - meaning that the bug is present in the following versions:

7.4.5196
8.0.5449
8.0.5449.1
8.1.5717

It's triggered running the following lines of code:

ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.impl.StaticLoggerBinder)));

I'm running on Mono JIT compiler version 4.6.2 (mono-4.6.0-branch/08fd525 Thu Nov 10 20:28:28 EST 2016)

You are probably mixing different ikvm runtimes or assemblies compiled with different versions of ikvmc.
