In this paper, we introduce a Java library for actors integrated seamlessly with futures and supporting coroutines. Coroutines allow actors to suspend the execution of a message and possibly schedule other messages before resuming the suspended continuation. As such coroutines enhance actors as a major building block for constructing software components. The library is used together with a compiler to generate code from an application model into an executable program in Java. A formal description of the translation process is provided together with the most important library methods. We highlight the importance of having a scalable and efficient implementation by means of some typical benchmarks which model a large number of tasks, coroutines and actors.
