Does Apache NetBeans 9.0 support java 11?

Can anyone say if Apache NetBeans 9.0 support java 11 and if so what are the requirements to make that work?

Prensently I can compile and run java 11 code in NetBeans 9.9 but it is underlined with red and the error message is "cannot find symbol ...".

Below is the pom.xml file I use:

How, for example pom-file should be changed?
