        FileOutputStream stream = new FileOutputStream(lockFile);
        //            FileInputStream stream = new FileInputStream(lockFile);
        FileChannel channel = stream.getChannel();
        //            FileLock lock = channel.lock(0,Long.MAX_VALUE, true);
        FileLock lock = channel.lock();
        stream.write(new UndocumentedJava().pid().getBytes());
        stream.flush();
        long start = System.currentTimeMillis();
        //            while (System.currentTimeMillis()-start < 10000) {
        //                Thread.sleep(500);
        //            }
        lock.release();
        stream.close();
        File f = new File(lockFile);
        System.out.println("Before write: " + FileUtils.readFileToString(f));
        FileUtils.writeStringToFile(f, "written after lock released");
        System.out.println("After write: " + FileUtils.readFileToString(f));
    } catch (Exception e) {
        e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
    }
