Hi, I do my development on an Apple Mac M1 using NetBeans 12.2
I downloaded the macOS Arm 64 bit version of jdk.15 from https://www.azul.com/downloads/zulu-community/?architecture=arm-64-bit&package=jdk installed the JDK and am running it in terminal at the moment until I trust it enough to change the NetBeans config. Terminal command as follows: "/Applications/NetBeans/Apache NetBeans 12.2.app/Contents/MacOS/netbeans" --jdkhome /Library/Java/JavaVirtualMachines/zulu-15.jdk/Contents/Home The result is that I have NetBeans running on an Arm native jdk which is, at a guess, 5 times faster than using NetBeans on a “normal” jdk. A maven project with 40 files builds in 2 or 3 seconds. There seem to be no problems with NetBeans and this version of Java. Hope that’s of interest. Regards David G
