[GitHub] [beam] reuvenlax commented on issue #24801: [Bug]: ReadableState.read() marked not nullable, but it does return null when not initialized

   @kennknowles ValueState (and related objects such as CombiningState) return null if the state has not been set yet, and this is how users check for that case today (related: adding a readWithDefault might simplify usage). This is a property of ValueState, i.e. it is true for every single type T in ValueState<T>
