I feel you are enumerating a whole bunch of workarounds you already thought about without giving us an example of the real issue you experienced.
Normally, modules can be installed and enabled and disabled by users are any time. If your app is somehow erratic now it means there's a hidden dependency not exposed. Maybe a module needs to provide / require some tags or maybe your module install needs to wait for something. So it could be a module problem or just a business logic problem: if a module prepares the DB in a background thread and the other module just starts using the DB right ahead, the modules could be loaded in the right order and still break the app due to a normal bug. --emi joi, 13 aug. 2020, 13:46 Patrik Karlström <pat...@trixon.se> a scris: > Lately I've been experiencing problematic behavior in a platform > application with close to 40 modules, NetBeans ones un-counted. > > I believe that it's related to the fact that I did not declare > any OpenIDE-Module-Module-Dependencies in the manifests and that the module > load order changed somehow. > > I do have a couple of platform books but I'm struggling with putting the > pieces together in order to secure my module dependencies. > > This led to the following questions: > > 1.
