The current implementation of the image builder sorts the modules by their name that are mapped to the same class loader. That explains why java.naming is the first one containing META-INF/services/java.security.Provider in your current list. There is no guarantee in what particular order a module is processed first. I don’t know if the jimage refresh work will change the ordering either. Since this is temporary, I’m okay if you want to depend on the image build implementation as long as you have a test to catch it and verify java.naming/META-INF/services/java.security.Provider file content. The existing security tests may also catch it but I think it’s not obvious to indicate that the security tests fail because of the issue of the merged service configuration file. Please also hold off until the image refresh change goes into jdk9/dev so that you can verify if your build change still works. If you want to push earlier, another alternative we discussed earlier is to separate the META-INF/services file and make change and java.security to keep using classname. That can be pushed that in a second phase with a proper image builder support.
