I've been keeping an eye for almost a year on swingx-ws (on SwingX website, via Google and whatnot [1,2, etc.]), to see if version 1.1 eventually made it to become a released milestone (I'm using v1.0 but there are some JXMapViewer bugs that, according to JIRA, are being addressed in v1.1).
Am I looking in the wrong places? Is development still active?
(If you can suggest a nice alternative library for dealing with online maps in Swing that you particularly like, please do)
EDIT: see this question for an update.
