Having used JNI multiple times before I would note that I would never use it again.

If the JNI code crashes then it takes the VM down. And there is little or nothing you can do to stop that.

For convenience I am going to refer to the needed non-java code as C/C++ below but it applies to any language that can be used to create an exe.

And there is a very viable option
1. Create a C/C++ wrapper which allows the target code to be run as and exe.
2. The exe has a control API. There are three ways to control it: Stdio, files or TCP/IP. Or perhaps pipes.
3. Use Java process API to run and manage the exe. That allows one to start, stop and kill it.
4. The Java code uses the control API to control it. This can include everything: configuration, passing binary data, statistics, health checks even a request for the exe to exit.

Advantages over JNI
1. It cannot crash the VM
2. The external code runs in its own process space.
3. The C/C++ code can be unit tested independently from Java code.
4. The C/C++ code is its own deliverable. Move the exe into the Java deployment space. It can even be packaged into a jar (any file can be) but of course it would need to be extracted into the file system.
5. The java code can be tested independently from the java code if the control interface is built carefully.
