In JSR 294 the superpackage feature for Java is specified. It should debut in Java 7, but the JSR is marked as inactive and Java 7 was released half a year ago.
Definite information on superpackages are somewhat hard to come by on the net, there are numerous articles on the 'upcoming superpackages', but hardly any on the current state of the feature. So my question is: What is the status of the feature?
I believe it is now called modules and should be part of Java 8 Java 9 - you can find more information in JSR 337 (search for module on the page). Modules are covered by Project Jigsaw.
