Description Alexandr Scherbatiy 2015-07-21 08:58:55 UTC 
Build: NetBeans Dev JDK9 branch (Build 201506180405)
VM: Java HotSpot(TM) Client VM, 1.9.0-ea-b73, Java(TM) SE Runtime Environment, 1.9.0-ea-b73
OS: Windows 7

User Comments:
GUEST: the error occured  during normal usage of the editor, scrolling over the hint to replace anonymous class with lambda expression. I can't do that as the source level is set to 1.6 - i also think that the hint should be adjusted to current source level setting

GUEST: 1)I have created a list
2)In ArrayList<String>();
3)After selecting the String I got the popup showing the NullPointerException

sunflower: edit code
