>  - Correct System.getLogger link
>  - Add an @implNote to Runtime.exit to describe the java.lang.Runtime logging.

>    Added test case with console logger (when java.util.logging) not present.
>    Removed @implNote tag its not appropriate in implementation javadoc.
>    Still looking into when and where the log configuration should be described.
>  - Locate the System logger before taking the shutdown lock
