Code Review: 7126889: Incorrect SSLEngine debug output

[Xuelei Fan]

The fix looks fine to me except some minor comments.

1. The copyright year should be 2012 now.

2. EngineArgs.java
     There is a resetPos() method in the class, which will reset 
application positions to original status. In the current fix, the 
"appRemaining" variable is not reset within the resetPos() method. As a 
result, after the call of resetPos(), the value of "appRemaining" 
variable may be not the expected value. For example,
     EngineArgs args = new EngineArgs();  // suppose the appRemaining 
value is 5
     args.gather(2);
     int remaining = args.getAppRemaining(); // remaining should be 3;
     args.resetPos();
     remaining = args.getAppRemaining();    // remaining is expected to be 5
                                                                         
// but indeed the value is 3.

The fix is OK in that in our implementation, once we reset the position 
of an instance of EngineArgs, we will abolish the instance and never use 
it any more.

To avoid any miss-use of this class in the future, I would like to have 
a method comment on resetPos() to talk about the note, or more effort, 
to reserve the original app remaining value and reset appRemaining to  
it in resetPos().

Thanks,
Xuelei
