We have the same problem, the workaround consists in forcing the precision of the depth buffer at 32 bits to make it work. Maybe it's really a bug.

I assume that, if the OpenGL driver based on an hardware rasterizer is unable to support any offscreen solution, JOGL uses another capability but with the wrong depth bits :s

Edit.: It's probably worse than I thought. I don't understand why and how it worked with an older version of JOGL. Maybe the real driver is totally unable to support FBOs and pbuffers or maybe something has been broken in JOGL and it makes it pick the wrong capability for the creation of an offscreen drawable (it uses the weak driver with the precision of the depth buffer suitable for the real driver).
