Some Classes with a public void close() don't implement AutoCloseable

[John Rose]

Nice.  I tried to find a way to make this a little more generic
and came up with an API which handles arbitrary exceptions
and is packaged as a method instead of a special idiom.
There’s a natural-enough method called `forceTryable` that
could be created.

https://bugs.openjdk.java.net/browse/JDK-8243015

(There are further generalizations of this, if you look at it as
a “named cast method” for a functional interface type related
to AutoCloseable.  See my comment on JDK-8243015.)
