Hey,
Did some debugging and found out that my class didn't contained =public=
and the patch requires it to be.
This works fine:
#+HEADER: :classname Main
#+HEADER: :dir src
#+HEADER: :cmdline -classpath ./rxjava-1.3.8.jar:.
#+HEADER: :cmpflag -classpath ./rxjava-1.3.8.jar
#+BEGIN_SRC java :results output code
import rx.Observable;
public class Main {
public static void main(String[] args) {
Observable.range(5, 5)
.subscribe(System.out::println);
}
}
#+END_SRC
