I resolved this problem by changing default version of JRE and JDK that I'm using to 11.x.x with following commands:

sudo update-alternatives --config java
sudo update-alternatives --config javac

Answer 3

This worked for me

1. install full JDK
2. either edit <netbeans-IDE-installation>/etc/netbeans.conf
    2.1 unmark netbeans_jdkhome
    2.2 link to JDK location e.g. /usr/local/share/java/jdk1.6.0_07/ 
3. or use --jdkhome command-line option e.g. ./bin/netbeans --jdkhome /usr/local/share/java/jdk1.6.0_07/ 

take care with the "/" at the end

Answer 6

In mid April 2019, Oracle has changed the JDK's licence. However, I was still able to solve this issue with NetBeans 11 and the JDK 12's open source build on my Windows machine. Just downloaded the open source JDK from https://jdk.java.net/ and extracted it. Then, in my NetBeans config file, I typed in the path to the extracted directory (NOT the "bin" folder!).
