Emulator Manager cannot run, had NullPointerException at startup

Emulator Manager cannot run, I need to setup another Tizen image but cannot do it; the pre-set image Package Manager set DOES run via Tizen Studio itself, but Emulator Manager could never run here, the call stack implies something null passed that should not be. Emu. Manager GUI does not provide information, just an error dialog. System is on an augmented unlocked Chromebook running Ubuntu GNOME 16.04 32-bit:

I uploaded the Java stacktrace, but where is it?

The Installantion guide says: "You must install a Java Development Kit (JDK) 8 or higher to use the Tizen Studio. Do not install OpenJDK."

If you are using OpenJDK may change it to Oracle JDK.

It is Oracle JDK 8, so that's not it

That's strange , I didn't faced such error or heard of it. I would suggest you to delete Emulator manager from Package Manager > Main SDK > Tizen SDK tools > Emulator manager > delete. Then install again. There is a chance of irregularity while installation.
