One good reason to refuse Jigsaw: it's far far too complex. I watched a whole hour and a half presentation on it, and the time was well necessary to explain the way things work and outline a migration path for existing code. The worst thing about it: I can't remember much about how it was supposed to work. I just remember that it was highly unintuitive, requiring both explicit imports and exports in specific files for each module. The fact that it is so tightly coupled to JDK refactoring also gives me pause. Seems like a design overfit. Both concerns should be handled separately. Sure a module system can help to separate out the JDK libraries, and that's certainly a nice way to check you've achieved your objectives with the design. But when this refactoring itself is one of the major justification for the design, something is wrong.
