I’ve just raised issue 4237. https://issues.apache.org/jira/browse/NETBEANS-4237
The key issue is: Launching <fx:deploy> in native packager mode... No base JDK. Package will use system JRE. No base JDK. Package will use system JRE. Bundler DMG Installer skipped because of a configuration problem: Cannot determine which JRE/JDK exists in the specified runtime directory. Advice to fix: Point the runtime directory to one of the JDK/JRE root, the Contents/Home directory of that root, or the Contents/Home/jre directory of the JDK. The advice given doesn’t work and so I can’t package. More details in Jira. Regards David Gradwell
