Greetings - welcome to Luna!
An Alpha1 version of the Eclipse Luna based JBTIS TP is now available in nexus . It's also available here  and an integration build of the current Luna JBTIS is available here .
I'm still working on dates but if we could get a first cut at the scope involved with upgrading that would help planning this thing immensely. There is SpringIDE and graphiti changes among others.
