Comments

Closing this as "Won't Fix". This is no longer an issue as of JDK 24 since the Security Manager (SM) has been permanently disabled (see JEP 486) and the ProtectionDomain cache has been removed since it is no longer needed. This may still be an issue in previous JDK releases where the SM is supported, so if necessary it could be re-opened at a later time and addressed for those previous releases.
