As explained in my email I tried this too, same problem.

Works fine. I'd like to use JDK23 with RELEASE240 cluster on my app, but I encounter weird problems. I run NB24 with Adoptium JDK23 on win11. Using compiler release=23 in parent pom. [ERROR] Failed to execute goal org.apache.netbeans.utilities:nbm-maven-plugin:4.8:manifest (default-manifest) on project xstream: Execution default-manifest of goal org.apache.netbeans.utilities:nbm-maven-plugin:4.8:manifest failed: Unsupported class file major version 67I found https://github.com/apache/netbeans-mavenutils-nbm-maven-plugin/issues/159 and used the fix proposed by guydaniel. This way I can compile the app but when I run it it starts but I get an empty/skeleton NB app, like my app modules are not loaded, without any error on the log. I checked the target which seem to contain all the required files. What happens ? Tried with release=22, same. Tried upgrading nbm to 14.2, which makes the danielguy fix above no more necessary.But I get : [INFO] --- nbm:14.2:manifest (default-manifest) @ yjzcreationwizard --- [INFO] NBM Plugin generates manifest [INFO] Private classes referenced in module: [org.jjazz.yamjjazz.YamChord] [ERROR] Project depends on packages not accessible at runtime in module org.jjazzlab.plugins:yamjjazz:jar:4.1.3-SNAPSHOT Error seems wrong to me, I checked, module yjzcreationwizard does not use the YamChord class. It only uses classes from module yamjjazz public packages. Workaround was to move the YamChord class to a public package, but it's not satisfactory. Anyway when I run the app I get the same problem, app runs but is "empty". Jerome
