@michaelsavich , this PR does not create a full dependency on
`java.desktop`. The dependency is expressed as `requires static`, which means
that it will not be pulled in by default. Users that want to use the two broken
classes on Java 9 in module mode (a very small percentage of commons-lang
users) will need to manually include the `java.desktop` dependency. As such,
there is no urgency to get `AbstractCircuitBreaker` removed.
