I've posted a development snapshot build that fixes the NullReferenceException in NewStringUTF. Can you try that? It is available here: http://www.frijters.net/ikvmbin-7.4.5046.zip Regards, Jeroen ________________________________ From: Danlourd Ramirez Sent: Thursday, October 24, 2013 3:48 PM To: Jeroen Frijters; ikv...@li... Subject: Re: [Ikvm-developers] Null Exception on IKVM.Runtime.JNIEnv.StringFromUTF8 Also this issue doesn't happen in all mac machine that we try it with. From what I can tell from the logs prior to the exception, the IKVM runtime is loading I18N.dll which then loads I18N.West.dll after some time the exception occurs. So I was wondering what the IKVM runtime is trying to do at this point. I know the I18N.dll and I18N.West.dll is for language code pages, does it mean the IKVM runtime, on some machines that we run our app, did not find languages and bombs out?

IKVM does not expect a null pointer to be passed to NewStringUTF. I will fix this in a future update. Thanks for reporting this.

I enabled mono debug logging and listed it below. The version of IKVM runtime is 7.2.4630.5 and we are using mono 3.0.1 that we bundled with our app. Can you help me figure out what could cause this issue?
