Answer 2

I had the same problem I installed NetBeans 8.2 on macOS High Sierra, and by default settings, NetBeans will work with the latest JDK release (currently JDK 9).

What I did was forcing NetBeans to use JDK 8, you must config your netbeans.conf file, you can find it on:

/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf

You need to uncomment and update your path to JDK, you will find yours at:

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

Just save it, restart NetBeans and you are done!

Answer 3

EDIT: The solution is to install JDK 8, as JDK 9 and beyond are currently not supported.

If however, you already have installed JDK 8, then kindly follow the steps outlined below.

The reason is that there is a conflict with the base JDK that NetBeans starts with. You have to set it to a lower version.

1. Go to the folder "C:\Program Files\NetBeans 8.2\etc", or wherever NetBeans is installed.
2. Open the netbeans.conf file.
3. Locate netbeans_jdkhome and replace the JDK path there with "C:\Program Files\Java\jdk1.8.0_152", or wherever your JDK is installed. Be sure to use the right path, or you will run into problems. Here, JDK 1.8.0_152 is installed.
4. Save the file, and restart NetBeans. It worked for me, should do for you too.

Answer 4

If you run in linux, open file netbeans.conf using nano or anything else.

nano netbeans-8.2/etc/netbeans.conf

and edit jdkhome or directory for jdk

netbeans_jdkhome="/usr/lib/jvm/java-1.8.0-openjdk-amd64"

you can check your jdk version with

java -version

or

ls /usr/lib/jvm

Answer 5

I had the same issue,

• Quit Netbeans.
• Delete the JDK9 file in : /Library/Java/JavaVirtualMachines
• Install the JDK8 : Download link

Good luck :)
