Futures in Scala 2.12 (part 8): Goodbye, sun.misc.Unsafe
Read OriginalThis technical blog post details the evolution of scala.concurrent.Future in Scala 2.12, specifically the removal of the sun.misc.Unsafe dependency. It explains the tri-state nature of a Future, the need for atomic Compare-And-Set operations, and the shift from using AtomicReferenceFieldUpdater and sun.misc.Unsafe to extending AtomicReference internally in DefaultPromise. The change improves platform compatibility and security while maintaining performance.
