PlantUML does not consider any of the system proxy environment variables like HTTP_PROXY or HTTPS_PROXY.

Java has a system property java.net.useSystemProxies to use system proxy varables in all http calls: https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html

The startup script under `/usr/bin/plantuml` can be updated to change this. If the last line in the startup script is changed with this one, it'd be fixed:

$JAVA -jar -Djava.net.useSystemProxies=true /usr/share/plantuml/plantuml.jar ${@}
