opendata depends on outdated Java EE modules

[james2432]

opendata plugin depends on javax.xml.bind and is no longer in Java9 and completely removed in Java 11. The only way to get around it in Java9 is to launch it with:

java -jar --add-modules java.xml.bind josm-latest.jar

As it is no longer in the default class path location

With openjdk 11.0.1 I am unable to bypass the error and ultimately unable to use the opendata plugin:
