I tried in windows using msys. I had the similar error.
Got the Java path (https://superuser.com/questions/1148677/finding-location-java-home-in-windows-10)
In msys export the path;
$ export PATH=$PATH:"/c/Program Files (x86)/Java/jre1.8.0_161/bin
It is working, able to see the flow diagram

suggestion:

Vim(not Nvim) job support start at version 8.
It means "Vim 7.4 is not supported at vim-slumlord currently".
