JNAerator self-extraction does not work

To reproduce, do the following (instructions assume you are using Linux, but I've also gotten the same result on win32 with the appropriate changes):
git clone https://github.com/leahxschmidt/testjnaerator.git
cd testjnaerator
make
cd java
javac -cp test_linux.jar:. JavaTest.java
java -cp test_linux.jar:. -Djna.nosys=true JavaTest

I would expect this to run correctly, but it does not.

If I first extract the jar and manually configure the library path, it does run:
jar xf test_linux.jar
java -cp test_linux.jar:. -Djna.nosys=true -Djna.library.path=lib/linux_x64/ JavaTest

Naturally, I don't want to have to do that. I don't have this problem if I use 0.9.7, but I do with 0.10.0.

Hi @leahxschmidt ,

It seems I've introduced a regression for the JNA(erator) runtime, indeed, thanks for your report (forgot to update LibraryExtractor.java when I updated the extraction scheme for BridJ).
While I'm working on a fix, you might want to give the BridJ runtime a go, though:

import java.net.InetAddress;
import java.net.UnknownHostException;

import org.bridj.*;
import static org.bridj.Pointer.*;

import org.getlantern.test.*;
import org.getlantern.test.TestLibrary.*;

public class JavaTest {

    public static void main(String[] args) {

            Pointer<Integer> address = /*Pointer.*/allocateInt();
        System.out.println("before");
        int result = /*TestLibrary.*/test(address);
        System.out.println("result = " + result);
        byte[] bytes = address.getBytes();
        try {
            InetAddress inetAddress = InetAddress.getByAddress(bytes);
            System.out.println("Default gateway is " + inetAddress);
        } catch (UnknownHostException e) {
            throw new RuntimeException(e);
        }
    }
}
