I find running something along the following lines in Terminal gives me complete control:
"/Applications/NetBeans/Apache NetBeans 12.3.app/Contents/MacOS/netbeans" --jdkhome /Library/Java/JavaVirtualMachines/zulu-15.jdk/Contents/Home Not as easy as a double click, but more secure if you have many versions of Java and many versions of NetBeans !

Hi, I’m having all sorts of issues with double-clicking on things in NB not always working. I suspect it’s because when I installed NB 12.3, I only had JDK 16 installed on my Mac and that’s what NB picked for itself - even though 16 isn’t supported as per the NB download site. How do I go into NB and tell it to use JDK 11 (which I’ve also got installed now) - do I manually edit the /Applications/NetBeans/Apache NetBeans 12.3.app/Contents/Resources/NetBeans/netbeans/etc/netbeans.conf file? This is on macOS BigSur. Thanks, Tom
