JDK 11 dependency tree displays only java.rmi module packages

[argherna]

Using VS Code 1.30.1, version 0.2.0 of the extension, when I expand the view under the JRE System Library [JavaSE-11] node, I see the modules as expected. However any module I expand only shows the contents of the java.rmi module. I expect to see the packages contained in the module (e.g. java.base should not display any of the java.rmi packages).
