OpenJDK issue no. 8148117: "Move sun.misc.Cleaner to jdk.internal.ref" [1],= will move the Cleaner class from sun.misc to jdk.internal.ref. There is on= going discussion about the possibility of providing a public supported API,= maybe in the JDK 9 timeframe, for releasing NIO direct buffer native memor= y, see the core-libs-dev mail thread [2]. At the very least CryptoStreamUti= ls & NativeIO [3] should be updated to have knowledge of the new location o= f the JDK Cleaner.
