Comment 3 Karol Harezlak 2008-11-25 16:09:45 UTC 
This problem is even deeper then I tough. It looks like some static non-final fields can be assign to the null
references and then problem is propagated to all Property Editors which use this value. Most likely this problem exists
in final release of 6.5. It is candidate for PATCH_2 for 6.5
