This new version has a lot of new features both for users and developers. For the user, new handlers managing white board pattern and extender pattern were added. This version supports Managed Service too, allowing dynamic reconfiguration of instances. For developer, this version generalizes method interception and so it is now possible to be notified of any entry, exit and error occurring in methods. Moreover, it improves greatly performances!
Last interesting feature, this version is fully supported on JamVM, Mika, J9, Harmony and JRockit. It is almost supported on Android VM (the nullable object injection is not supported as dynamic proxies are not supported on Android; however the default-implementation pattern is supported).
