> sun.misc.Cleaner is not available since Java 9.
> It was moved to jdk.internal.ref.Cleaner of java.base module ([Open JDK-8148117|https://bugs.openjdk.java.net/browse/JDK-8148117]),
but another new public API  was introduced to achieve the same behaviour (java.lang.ref.Cleaner);
> A popular solution is use reflection to look up for the location of the Cleaner class
depending on running JVM version.
