This object provides extension methods that convert between Scalascala.concurrent.Future and Javajava.util.concurrent.CompletionStage

When writing Java code, use the explicit conversion methods defined injavaapi.FutureConverters instead.

Note that the bridge is implemented at the read-only side of asynchronous handles, namelyscala.concurrent.Future (instead ofscala.concurrent.Promise) andjava.util.concurrent.CompletionStage (instead ofjava.util.concurrent.CompletableFuture). This is intentional, as the semantics of bridging the write-handles would be prone to race conditions; if both ends (CompletableFuture andPromise) are completed independently at the same time, they may contain different values afterwards. For this reason,toCompletableFuture is not supported on the createdCompletionStages.
