The most risky bug in this code is:
The casting in the readJson method may lead to a ClassCastException.
You can modify the code like this:
@Override
public <T> T readJson(Class<T> classOfT) throws IOException, SRMetaBlockEOFException {
Object object = readJson((Type) classOfT);
if(!Primitives.wrap(classOfT).isInstance(object)) {
throw new JsonSyntaxException("Expected type " + classOfT.getName() + " but got "
+ (object == null ? "null" : object.getClass().getName()));
}
return Primitives.wrap(classOfT).cast(object);
}

The most risky bug in this code is:
Potentially throwing IOException within the lambda functions of readMapEntry, which may not be adequately handled and could be suppressed.
You can modify the code like this:
public void loadV2(SRMetaBlockReader reader) throws IOException, SRMetaBlockException, SRMetaBlockEOFException {
// 1 json for myself
AuthorizationMgr ret = reader.readJson(AuthorizationMgr.class);
ret.globalStateMgr = globalStateMgr;
ret.provider = Objects.requireNonNullElseGet(provider, DefaultAuthorizationProvider::new);
ret.initBuiltinRolesAndUsers();
try {
LOG.info("loading users");
reader.readMapEntry(UserIdentity.class, UserPrivilegeCollectionV2.class,
(MapEntryConsumer<UserIdentity, UserPrivilegeCollectionV2>) (userIdentity, collection) -> {
if (userIdentity.equals(UserIdentity.ROOT)) {
try {
UserPrivilegeCollectionV2 rootUserPrivCollection =
ret.getUserPrivilegeCollectionUnlocked(UserIdentity.ROOT);
collection.grantRoles(rootUserPrivCollection.getAllRoles());
collection.setDefaultRoleIds(rootUserPrivCollection.getDefaultRoleIds());
collection.typeToPrivilegeEntryList = rootUserPrivCollection.typeToPrivilegeEntryList;
} catch (PrivilegeException e) {
throw new RuntimeException("failed to load users in AuthorizationManager!", e);
}
}
ret.userToPrivilegeCollection.put(userIdentity, collection);
});
LOG.info("loading roles");
reader.readMapEntry(Long.class, RolePrivilegeCollectionV2.class,
(MapEntryConsumer<Long, RolePrivilegeCollectionV2>) (roleId, collection) -> {
// Use hard-code PrivilegeCollection in the memory as the built-in role permission.
// The reason why need to replay from the image here
// is because the associated information of the role-id is stored in the image.
if (PrivilegeBuiltinConstants.IMMUTABLE_BUILT_IN_ROLE_IDS.contains(roleId)) {
RolePrivilegeCollectionV2 builtInRolePrivilegeCollection =
ret.roleIdToPrivilegeCollection.get(roleId);
collection.typeToPrivilegeEntryList = builtInRolePrivilegeCollection.typeToPrivilegeEntryList;
}
ret.roleIdToPrivilegeCollection.put(roleId, collection);
});
LOG.info("loaded {} users, {} roles",
ret.userToPrivilegeCollection.size(), ret.roleIdToPrivilegeCollection.size());
// mark data is loaded
isLoaded = true;
roleNameToId = ret.roleNameToId;
pluginId = ret.pluginId;
pluginVersion = ret.pluginVersion;
userToPrivilegeCollection = ret.userToPrivilegeCollection;
roleIdToPrivilegeCollection = ret.roleIdToPrivilegeCollection;
// Initialize the Authorizer class in advance during the loading phase
// to prevent loading errors and lack of permissions.
Authorizer.getInstance();
} catch (RuntimeException e) {
throw new IOException("Failed to load AuthorizationManager!", e);
