Description
Netbeans throws a NPE when I try too pull a method from a class to an interface it implements. In the "Pull up" window the method I wanted to move was selected and marked as "Make Abstract. Also the other methods in my class were marked as "Make Abstract", although not selected.
This is the exception stack trace:
