Here's what's going on with WTP:
1) WTP builds still moving to JIRO (bug 568553):
Still a work in progress. It's a good place for someone who wants to contribute in a way other than working on code.
2) Jakarta EE, 9 and above*:
Bug 565498, about the Servlet/Listener/Filter wizards, is foremost on my mind--but it seems like it'll have to wait until 3.22. The most visible part of the JSP work is complete; what remains has been spun off to a different bug for 3.22, as well.
