Java SE Development Kit 9 is not compatible with the Netbeans IDE 8.2.
My Solution:
- Delete the current JDK 9
- Install this previous trust version of JDK: JDK 8
- Modify the following file: \Program Files\NetBeans
8.2\etc\netbeans.conf to the given folder path of the newly installed JDK 8: netbeans_jdkhome="C:\Program
Files\Java\jdk1.8.0_151" (example)
