OzoneAclUtil.java ``` public static boolean setAcl(List<OzoneAcl> existingAcls, List<OzoneAcl> newAcls) { if (existingAcls == null) { return false; } else { existingAcls.clear(); if (newAcls != null) { existingAcls.addAll(newAcls); } } return true; } ``` setAcl logic used by Bucket/Volume/Key SetAcl. if new Acls are being set we just override and return true. and top existingAcls == null will mostly not happen, as we set in builder like below. OmBucketInfo.java L256: ``` public Builder() { //Default values this.acls = new ArrayList<>(); this.isVersionEnabled = false; this.storageType = StorageType.DISK; this.metadata = new HashMap<>(); } ```
