--------------------------------------
Summary: NullPointerException with "Pull up" refactoring
Key: NETBEANS-2245
URL: https://issues.apache.org/jira/browse/NETBEANS-2245
Project: NetBeans
Issue Type: Bug
Components: java - Refactoring
Affects Versions: 11.0
Reporter: Aldo Brucale
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:
