Patching module content is intended for testing and debugging use and a corner case. Developers may want to find out which modules are patched or possibly what classes would be patched. If we had to introduce a system property about patching, would it be more useful to include the name of the modules being patched? ------------- PR Comment: https://git.openjdk.org/jdk/pull/22277#issuecomment-2501579406
