When Tapestry loads a service it creates a new class loader for it. The service class and its inner classes and base classes are loaded by that class loader, but it causes problems accessing non-public members of other classes in the same package: it's not really the same class or the same package, it just shares the package name and class name. A very, very leaky abstraction (one of the reasons I didn't attempt live service reloading earlier it because its impossible to do it "right" without much more intrusive technology, such as an agent). When you bind() a service, you can now explicitly disable live service reloading for that one service, see ServiceBindingOptions. > You might suggest to simply change the scope of these methods and classes but > we can't easily re-factor our library modules because of the sheer scale, and > even if it were an option, and we did consider it for a time, these errors > produce runtime exceptions, which makes it is very difficult to find every > occurrence in the code, so for us to change the scope for our entire IoC > codebase is not a practical solution.
