3D physics library

I am looking for suggestions on a good 3D physics library. I have googled this question and jbullet seems to be the best answer, but having not been updated since 2010 slightly concerns me and I want to be sure that it is a good library before I commit to it. So, I guess my question is does anyone know of a good 3D physics library or is jbullet the best option.

At the moment, JBullet is the best option and works very well for rigid-body physics. I think the new JMonkeyEngine might have a modified JBullet embedded that might be updated more frequently.
