- Moved all the remaining NIO logic from previous internal HTTP connector to the
        org.restlet.ext.nio. This will help reduce the org.restlet.jar file size.
      - Issue #805: The NioUtils.copy(..) logic that sometimes created Cyclic barrier
        exceptions has been moved as well and replaced with the older and more stable
        logic that was in place in version 2.1.0 and older releases.
