We are starting a new project named "Dojo". Dojo is a Java 1.5 clean container implementation. The very initial scratch code has been uploaded, and it has no features at this point. Work will continue on GUIApp in the meantime using Fortress. When Dojo is mature enough, we will likely migrate GUIApp over. By that time, Java 1.5 will be mature and not a beta any more, and the IDEs available will be supporting the new JDK.
