That test looks familiar… hehe. 
Thinking about this more, the problem is probably a lack of updateRenderState. The original version of the test did not have that as it is not needed in Ardor3d. Hope that helps!

yep, i hope its ok to 'steal' the test :)
updating renderstates (root- graph- or statnode) didn't help.
hmm thats funny, i tried this again on my other pc, and here it works just fine.
ATI X1400 Mobility + lwjgl -> problem
" + jogl -> Ok
NVIDIA GeForce 9600 lwjgl and jogl -> Ok
Anyway, the test is committed.
