Hi All, I encounter the same problem than Sander in [1] regarding automatic modules and Jlink. My project has a lot of modules and uses a lot of dependencies (Java EE spec and impls) so it took me a few days to walk thru the writing of all my module-info.java files. hopefully I only found 2 automatics modules from 3rd parties that had split packages and propose PR to these project to correct these, in the meantime I use personal snapshot version for my JDK9 compilation. At the end everything compiled fine without using classpath, but how frustrating it was to discover that I was unable to use Jlink because of this automatic module limitation.
If you put my experience in perspective, it means that if you depend on tens of dependencies you'll have to wait months, even years before other projects decide to switch to JDK9 letting use use this great Jlink feature. IMO, if this limitation is not solved it may reatard jdk9 adoption on a lot of projects. I guess it's easier to say than do, but having a solution to externally add meta-data to these automatic modules (an kind of external module-info.class) could be doable for a more advance bridge approach. Anyway, thanks for all the great work and your feedback. Antoine Sabot-Durand [1] http://mail.openjdk.java.net/pipermail/jigsaw-dev/2016-March/006526.html
