Java 6 file IO - installment 5678657

Primer
The not so standard idiom - see an answer there for varargs close() method. And another answer with useful info.

On closing only the outermost buffer : consider (also a bug) -  I actually commented on this here and here

Comparison of the :

final Resource resource = acquire();
try {
    use(resource);
} finally {
    resource.release();
}

pattern (see also other answers there - a wealth of info) to the traditional : 

Resource resource = null;
try { 
    resource = acquire();
    use(resource);
} finally {
    if(resource != null) resource.release();
}

(also in DB code)

And a question concerning multiple wrapped streams

Btw At what point does wrapping a FileOutputStream with a BufferedOutputStream makes sense,
in terms of performance? with interesting links to source

Advanced
Execute around idiom - Skeet - read in your free time, still escapes me.
class Compensation - well that's a good one ! Unfold the try finally block ! Comments like in the Skeet answer apply.

Android Sleep - Link collection

Wake locks are not released on activity onPause/onStop, not suprisingly

Bad news : receivers are mostly not woken up.

Does the Android OS release a wakelock if the app or service holding it is killed?  It is unanswered.
Also have a look here, answered in the affirmative and android app lock required for socket connection? for err socket connections.

Beginner questions: Wakelocks, check the answer and also What's the best between AlarmManager and Handler+WakeLock? for links to the docs as well as AlarmManager's wake lock when starting a service and BroadcastReceiver, Service and Wakelock  answer.

And from google groups : When does the platform hold wakelocks? as well as Observation and comments on Android and "regularly" scheduled events.

 And the wakeful manual.
