Travis commented on NETBEANS-3019:
----------------------------------
Doing the exact same thing without nb-javac installed does not encounter any
exception. But it also fails to identify and automatically add 2 of the 3
necessary imports during the "Import Classes" dialog. Running "Fix Imports"
afterward does correctly add the other 2 missing imports, however.
So this exception seems to be only reproducible with nb-javac installed.

> Key: NETBEANS-3019
> URL: https://issues.apache.org/jira/browse/NETBEANS-3019
> Project: NetBeans
> Issue Type: Bug
> Components: java - Source
> Affects Versions: 11.1
> Reporter: Travis
> Assignee: ARUNAVA SINHA
> Priority: Major
> Attachments: netbeans-3019-test-project.zip

> I got the exception below in a fresh installation of Netbeans 11.1. This is
> after I installed nb-javac 1.6, but zero other plugins. I'm using Gradle 5.5
> on Windows 10, but that probably makes no difference here. Netbeans is
> running on OpenJDK 12 and the project is also being built using Java 12.
> The bug can be reproduced using the attached small project, which I
> painstakingly distilled out from a large code base where this bug was first
> found. To trigger the exception, you need to copy "CopyMe" from Source.java
> and paste it into Destination.java. Upon pasting, the "Import Classes"
> dialog will appear. Immediately after pressing the "OK" button, this
> exception happens:
