It's not dead, it's just really slow. The 2.7 release has been very long in the making, released only 18 months ago. There are stabilization releases to it still coming out. There's a tiny, but dedicated group building it and it shows. Jython 3 is possible if you're willing to put your money where your mouth is.
Yes, that would be true on all counts :) as one of those Jython maintainers. Jython 2.7.1 is currently bottlenecked on finalizing support on Windows for pip/setuptools. It should be the last fix.
