That is correct. > I'd imagine that the effect would be instead visible for self-contained distributions, like e.g. docker containers. In theory. In practice you need to build a JDK contains only the bits you need. Sounds great in theory, you can get rid of the CORBA and GUI modules, that should save you a lot of disk space. In practice the CORBA module is only 2.7 MB and the desktop module is 14 MB and almost every framework indirectly requires the desktop module because Java Beans are in there.
