Travis commented on NETBEANS-2956:
----------------------------------
Oh dear. I've wasted my time due to the confusing maze of Netbeans exceptions
on Java 12. It turns out this exception goes away when nb-javac is installed.
Therefore this ticket is not worth much.
> AssertionError during background scan of a Java 12 project

> Key: NETBEANS-2956
> URL: https://issues.apache.org/jira/browse/NETBEANS-2956
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 11.0, 11.1
> Reporter: Travis
> Priority: Major
> Attachments: netbeans-2956-test-project.zip
>
>
> It seems that there are still some tricky bugs lurking in Netbeans when
> running with Java 12 projects open.
>
> My environment is:
> Netbeans 11.1 <-- a totally fresh installation, no plugins installed (not
> even nb-javac)
> OpenJDK 12 <-- Netbeans is running on this JDK, and also my project is built
> using this JDK
> Gradle 5.5
> Windows 10
>
> During background scan of the attached project, I get the following
> exception:
> java.lang.AssertionError: Analyzer error when processing: container.drink(new
> FooBuilder<Bat>(slug).matches(bug));java.lang.AssertionError: Analyzer error
