C# program using a sphinx4 .jar converted to .dll fails

Question

When I try to instantiate the LiveSpeechRecognizer, it throws an error which gives the following stack trace:

Exception thrown: 'edu.cmu.sphinx.util.props.PropertyException' in VoiceRecognition.dll
   at edu.cmu.sphinx.frontend.AutoCepstrum.newProperties(PropertySheet ps)

   at TestingStandaloneCSVoiceRecognition.Program..ctor()

I"ve been trying to sift through the documentation and code to figure out what's causing it, but I've had little luck so far. I should probably note that I used IKVM to convert the .jars to a .dll which I've imported into a Visual Studio C# project. The LiveSpeechRecognizer doesn't even finish instantiating before throwing the error. I've made sure that I've imported all dependencies, so that's not the issue. The java program works fine.

It is a bad idea to call java code from C#, instead you can simply use pocketsphinx dll with C# API, see

I've been working on trying to do that, but I'm struggling to get swig working right. – Astrolamb Oct 23 '18 at 11:50
What is your problem with swig exactly? – Nikolay Shmyrev Oct 23 '18 at 15:11
I just don't know how to use it yet I think. I'm using windows, and the .exe provided for use with windows doesn't do anything. – Astrolamb Oct 24 '18 at 16:26
