can't open netbeans IDE in Fedora 17

view full story

http://unix.stackexchange.com – my linux version is: Fedora 17 I installed Netbeans IDE 7.1.2 and it was working fine, but now, when I try to open it, nothing happens after double clicking on it. I think updating the kernel may be the reason, my current kernel version is : 3.4.3 do you know the exact reason and how to solve it? (HowTos)
