Projects Window is not opening, showing error in log

ashutosh.dvlpr
Suddenly my netbeans stopped showing Project Window when I changed java folder.
I reinstalled it 3 times, but still I am not able to see window. I have even tried deleting all folders of netbeans which are found in AppData and Roaming.

I am also attaching and pasting the log I get whenever I am selecting Projects in Window option.
