its very helpful and very strange
so it propably depends on my graphic card ;/
i have no time to write algoritms. i will try to test it on other Machines (maybe my graphic card is just a anomaly)
Test case works also for me, iām afraid itās an hardware issue, did you try newer drivers ?

yes i already tried older and newer drivers. But still all show itās hardware.
Itās bad news becouse not only me can have this problem.
Good is this that it really work(but not for me).
Tnx for help 
For you(developers) i can tell i have a āMobile IntelĀ® 4 Series Express Chipset Familyā (it use memory from RAM) to notice it
Sounds like crummy hardwareā¦ (sorry) 
Oh Intel GM are not the best graphic cards around indeed, Some other users already had some quirks with those kind of cards.
Is there a way for you to test on some other hardware?
Tested that testcase with my ati 4870 card (and jme3 from svn, compiled yesterday):
moved the camera near to the shadow, it seems to render fine, but sometimes
when I rotate the camera just a litte bit, shadow disappears.
Tested different values when initializing (shadowmap sizes, splits, comparemodes, filtermodes) but always same disappearing.
yes i have other hardware to test, im just surprised that shadow donāt work everywhere

Oh yes, I did see this too once or twice but lost track of the location/angle it was vanishing, and couldn't reproduce.
