JRE fatal error while using OpenNI java wrapper - java-native-interface

Question

Im trying to record a depth map to an .oni file with OpenNI using the java wrapper. This is my current code:
Context context = new Context();
DepthGenerator depth = DepthGenerator.create(context);
Recorder recorder = Recorder.create(context, null); //null gives .oni.
recorder.addNodeToRecording(depth);
context.startGeneratingAll();
while(true){
context.waitAnyUpdateAll();
recorder.Record();
}
When Im running it, this error is produced:
A fatal error has been detected by the Java Runtime Environment:

Anyone have any ideas?

Answer 1

I figured it out.
Recorder recorder = Recorder.create(context, "oni");
I needed to specify the file format. Passing in a null value was not the best idea obviously.
