According to the image from here

both libraries work according to the same principle. But I believe that there is a difference between them. What is this difference?

The presentation you linked gave part of the answer already - so just continue reading. E.g. on slide 26 and ff:

Why Not JNA?

  • Preprocessor constants?
  • Standard API sets out of the box
  • C callbacks?
  • Performance

JNA uses reflection to call native methods.

JNR generates bytecode in runtime only once therefore JNR works faster then JNA. See example of code generating here
