Add the doPrivileged in the main method:

    public static void main(String... args) throws Throwable {
        try {
            AccessController.doPrivileged(new PrivilegedExceptionAction<>() {
                @Override
                public Void run() throws Exception {
                    new Main(System.err).run(VM.getRuntimeArguments(), args);
                    return null;
                }
            });
        } catch (PrivilegedActionException pae) {
            Throwable e = pae.getCause();
            if (e instanceof Fault) {
                System.err.println(e.getMessage());
                System.exit(1);
            } else if (e instanceof InvocationTargetException) {
                // leave VM to handle the stacktrace, in the standard manner
                throw e.getCause();
            }
        }
    }

And also add doPrivileged around new URL call and grant AllPermission to 
jdk.compiler
