java.io.FileInputStream -The type initializer for 'java.io.File' threw an exception

Question

I am trying to use OpenNLP.Net Nuget package. I created a sample project but running into TypeInitialization exception when java.io.FileInputStream object is created.

"The type initializer for 'java.io.File' threw an exception."

Any ideas?

My IKVM.net version number is 7.4.5196.0, VS2013, .NET 4.5

Thanks

Edit:

I am trying sample code from here but using the nuget package: https://cwiki.apache.org/confluence/display/OPENNLP/Introduction+to+using+openNLP+in+.NET+Projects

Exception ToString() is "The function evaluation was disabled because of an out of memory exception". 
_Hresult = -2146233036 
_message = The type initializer for 'java.io.File' threw an exception.

Here is the stack from IntelliTrace:
