> @vicente-romero-oracle It is difficult to identify which test should be changed, because all the tests passed. As you said, the `TargetAnnoCombo.java` maybe need to be changed. I want to revise it now. Should I do it?

sure please, I think that you should not only check that that test passes but also modify it, explicitly adding cases for the MODULE target. As a general comment this change is simple but the implications are not. I think the patch needs to add more tests. We also need to test that annotation processors can `see` the annotation applied to modules, etc.
