Yes, with the `allPermEntryFound` flag, the current fix would not require to put the `javax.crypto.CryptoAllPermission` entry in `processedPermissions`. So `processedPermissions` will be used to keep `javax.crypto.CryptoPermission` entries and is updated by `isConsistent()`, and no need to deal with `javax.crypto.CryptoAllPermission` entry. I’d like to keep it as-is if there is no objection.
