I adjusted the UL settings again, and now I see the 'bad'  output


[0.010s][error][cds] An error has occurred while processing the shared archive file. Run with -Xlog:aot,cds for details.
[0.010s][error][cds] Mismatched values for property jdk.module.addexports: java.base/sun.security.util=ALL-UNNAMED specified during runtime but not during dump time
[0.010s][error][cds] Disabling optimized module handling


in the `build.log` as expected and not any more in the `blocked.certs`  file , where we don't want to see it .
