Here is my java version

java -version openjdk version "11.0.2" 2019-01-15 OpenJDK Runtime Environment (build 11.0.2+9-Ubuntu-3ubuntu118.04.3) OpenJDK 64-Bit Server VM (build 11.0.2+9-Ubuntu-3ubuntu118.04.3, mixed mode, sharing)

The cause is for using java-11-openjdk-amd64

open terminal and run 

sudo update-alternatives --config java

and choose java-8-openjdk-amd64

and run vega again.
