Description
A DESCRIPTION OF THE PROBLEM :
With JDK-8264777, i suggested to overload optimized FileInputStream::readAllBytes.

The same improvement could be done for java.nio's java.nio.file.Files.newInputStream().readAllBytes() - which is still as slow as before.

I suggest to overload sun.nio.ch.ChannelInputStream::readAllBytes with the same algorithm as FileInputStream::readAllBytes. 
See JDK-8264777 / FileInputStream::readAllBytes of JDK17 for details.
