it exposes the same functionality, though as the coroutines guide points out you likely want to name the method doXAsync, something like

//for kotlin callers
suspend fun doHeavyLifting(args: Arg){

}

//for java
fun doHeavyLiftingAsync(args: Arg): CompletableFuture<Whatever> = future { doHeavyLifting(args) }
