Twisted in Java

Question

What is the closest Java alternative to Twisted?

Answer 1

If there is still an interest in this, I've just put up the first beta release of the 'Reaction' framework, which supports the Twisted-style deferred callback model in Java. As well as working as a standard Java package, it can also be used as an OSGi service. License is Apache version 2.
