UncheckedAutoCloseable narrows AutoCloseable.close() to not throw. There is a widely known duplicate, [Registration|https://www.javadoc.io/doc/org.opendaylight.yangtools/yangtools-docs/latest/org/opendaylight/yangtools/concepts/Registration.html,] which does the same thing. In addition to UncheckedAutoCloseable, it also provides a useful default implementation.
