> - The `NamingManager` class-level documentation is edited to remove references to the `SecurityManager`. It was also revised to clarify a reconstruction mechanism of object factories from remote references in the presence of a custom `ObjectFactoriesBuilder`.
> - Also, the modified classes have been cleaned-up from `SecurityManager`, `doPrivildged`, and `AccessController` usages.

> These changes require a CSR that will be submitted soon.

> ### Testing
> - Added a new test to check if NamingManager#setObjectFactoryBuilder can be used to implement remote code downloading: `test/jdk/com/sun/jndi/rmi/registry/objects/ObjectFactoryBuilderCodebaseTest.java`
> - `jdk-tier1` to `jdk-tier3` and other JNDI LDAP/RMI tests show no issue with the proposed changes.
