With the removal of the AltFinalizer mechanism from `FileInputStream` and `FileOutputStream` in [JDK-8192939](https://bugs.openjdk.org/browse/JDK-8192939), this portion of the Implementation Requirement in the class JavaDoc is no longer true:
> If this FileOutputStream has been subclassed and the close() method has been > overridden, the close() method will be called when the FileInputStream is > unreachable." The class doc, and the doc for close(), are updated to correctly reflect current behavior, and guidance for subclasses is clarified. ------------- Commit messages: - remove blank line - Clarify that finalization isn't used for cleanup for FIS/FOS, and that Cleaner should be used instead.
