The implementation of these classes do not close the given `Deflater`/`Inflater` when the corresponding instance of the class itself is closed. This isn't documented and can lead to situations where callers aren't aware that they are responsible for closing the given `Deflater`/`Inflater` instance. That can then lead to resource leaks of resources held by the `Deflater`/`Inflater`.

I chose the `@implSpec` since each of these classes whose documentation is being updated are `public` and can be sub-classed and the `close()` method overridden. The text being added merely specifies the implementation of these classes and not the sub-classes.

Thank you everyone for the inputs and help on taking this to completion. The CSR has been approved. I'll go ahead and integrate this now.
