If javac will try to load them (while discovering annotations for the purpose of detecting which annotation processors should be run), an error will be produced (please see the issue). The proposal is to strip annotations that are not present in ct.sym when generating ct.sym.

shouldn't PREVIEW_FEATURE_ANNOTATION_INTERNAL be added to HARDCODED_ANNOTATIONS too?
