Prakash Ramrakhyani e4830ad2eb gem5ops: Implement Java JNI for gem5Ops
These ops allow gem5 ops to be called from within java programs like the following:
import jni.gem5Op;

public  class HelloWorld {

    public static void main(String[] args) {
        gem5Op gem5 = new gem5Op();
        System.out.println("Rpns0:" + gem5.rpns());
        System.out.println("Rpns1:" + gem5.rpns());
    }

    static {
        System.loadLibrary("gem5OpJni");
    }
}

When building you need to make sure classpath include gem5OpJni.jar:
javac -classpath $CLASSPATH:/path/to/gem5OpJni.jar HelloWorld.java

and when running you need to make sure both the java and library path are set:
java -classpath $CLASSPATH:/path/to/gem5OpJni.jar -Djava.library.path=/path/to/libgem5OpJni.so HelloWorld
