[Solved] Unable to install Netbeans 8.* on Debian (Stretch)

[Ravi Joshi]

Hello,
I have trouble installing Netbeans (especially C++ module) in Debian Stretch.
When I launch the installer of Netbeans 8.1 (downloaded from netbeans.org), the dialog box which provides for customization starts but stays unresponsive. No button is clickable (customize, Next, Cancel). The 'x' close button too is unresponsive.
I have tried 8.0 and 8.1 both.
Can someone please help?

Env:
1. OpenJDK 7 is installed.
2. I dual boot Debian Stretch (primary) with Ubuntu Vivid (secondary). On Ubuntu I can install.
3. In previous Debian Strech (which I had to remove and reinstall it again) I could install netbeans - so it's not likely a debian issue (nor KDE or GNOME).
4. I have used apt-get to install netbeans currently. But the only Java module is present. There is no way to install C++ part.

Thanks in advance for any help.

I am able to install Netbeans with the installation and choosing of Oracle JDK instead of OpenJDK.
Thanks.
