The type initializer for 'java.nio.charset.StandardCharsets' threw an exception.

Hi ,
I am using IKVM to convert WEKA to dll and I have used it in my windows 8 app.
I am doing this in visual studio 12. Then I have used example given on the
WEKA site to test the working but it gives me run time error
 "The type initializer for 'java.nio.charset.StandardCharsets' threw an
exception."

Can any body solve this?
