Fatal error during program launching

Hi,

I’ve installed MEGAN 6 on my laptop with Ubuntu 16.04 LTS. When i tried to run it i found error message in the program error.log file:

MEGAN fatal error:
java.lang.NoClassDefFoundError: javafx/embed/swing/JFXPanel

When i typed in the Unix console java -version , i got:

openjdk version “1.8.0_151”
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

What is wrong with my installation? How can i fix it?

Regards,
Denis

MEGAN requires the Oracle JRE
