Hi Eirik,
check the project.properties of the module in question.
if it has:
javac.source=1.8
btw the reason why javac says that it can't see the class is because the
'-source' property is mapped to '-release' under certain conditions by
the custom ant task which runs javac. And the release option links to
the specified version of the JDK API (which is a good thing).
https://github.com/apache/netbeans/blob/b9cadbc946b1d42553efd528fee856178798c681/platform/openide.util.ui/nbproject/project.properties
at some point we will only have
javac.release=xx
but for now its better to use the source+target combo as mentioned before
-mbien
replace it with:
javac.source=11
javac.target=11
after that you could put this into manifest.mf:
OpenIDE-Module-Java-Dependencies: Java > 11
modules which use nb-javac are a special case, i plan to put that into
a meta issue since that is more complicated and we have to take
special care in CI for that.

Hi, netbeans-dev.
Normally I build NetBeans from sources by just running the command
"ant" from the root of the repo.
While making some improvements to the
platform\openide.util.ui\ImageUtilities class, I concluded I need to
use the java.awt.image.MultiResolutionImage class, which only became
available in JDK 9. With a plain "ant" build I get a "cannot find
symbol" error when referencing it.
What build option do I need to set to build NetBeans on a newer Java
version, and get access to the Java 9 APIs from the openide.util.ui
module?
My JAVA_HOME environment variable is already pointing at Java 11.
(The specific use case here is to make SVG/HiDPI/Retina icons work in
the main menu bar on MacOS, for my NetBeans Platform application.
This requires use of the MultiResolutionImage class.)
