i'd recommend lwjgl, its small, fast and maintained at a steady pace. also it gives you access to all the stuff needed for games development and lets you just get on with the job.
Not sure I fully understand the scope, is the team big enough to support it, advantages vs JOGL?
yes the team is pretty competent and skilled to support it
(at least from my observations, i hope
), latest release was yesterday, development it moving at a very nice pace.
as for advantages one that pops to mind is that lwjgl has a much lighter memory footprint as it less intangled with awt.
