issue: https://bugs.openjdk.java.net/browse/JDK-8145419
webrev: http://cr.openjdk.java.net/~onazarkina/8145419/

Last buffer such as buffer.remaining() != 0 is marked with respective 
attribute to trigger a stop condition. Besides, an unexpected IAE 
doesn't occur (JDK-8144994 
<https://bugs.openjdk.java.net/browse/JDK-8144994>​) anymore.
