public final class AsyncClosureUtils
extends ObjectClosure-specific async utilities that have no pure-Java equivalent.
These methods create Closure subclasses and are therefore
inherently Groovy-specific. They predate the async keyword
and are retained for programmatic use. The async { ... }
keyword syntax is preferred for most use cases.
