Geertjan Wielenga commented on NETBEANS-2135:
---------------------------------------------

Been looking into this, something about the POM, that's for sure. It should work, just not sure why. When I use the latest builds of Apache NetBeans 11 with JDK 12 rc, and create a new Maven project, with this POM and a module-info.java, everything is fine. Maybe try to set the below up yourself and confirm (in 10 is also fine with JDK 11 is also fine, then put 11 below where I have 12) and I'll continue to investigate.

> I am experiencing false positive parser error messages in the Java editor when working on a Java Maven project.
> I can check out the project, compile it and run alle Unit tests, but the editor lists many errors. 
>  * modules are not supported in -source 8 (use -source 9 or higher to enable modules)
>  * package X does not exist
>  * cannot access java.lang Fatal Error: Unable to find java.lang in classpath or bootclasspath
>  * cannot find symbol
> It is easy to reproduce. Just check out the GitHub project ThreeTen-Extra and open the directory with NetBeans.
