no it is not. There are seveal ways how to bundle native libraries.
jpackage is one way, fat jars are another. And for fat jars of course
you can extract native libraries at runtime (JNA does exactly that).
What is difficult is the handling of native dependencies. If you know
what you are doing you can manually load native libraries in the right

The alternative is to distribute a ZIP file and setup the paths prior
to loading libraries. Changing the java.library.path takes some
reflection, but it is possible to do at runtime.

The javafx jars from maven central hold the native libraries.
