Remote code downloading in JNDI has been disabled by default since 8u121.
Two system properties were introduced at the time to allow to selectively reenable remote code downloading in JNDI/LDAP and JNDI/RMI.
With the deprecation and upcoming removal of the SecurityManager (see JEP 411: https://openjdk.org/jeps/411), this enhancement proposes to remove these two properties and permanently disable remote code downloading in JNDI/LDAP and JNDI/RMI.
The two properties proposed for removal are `com.sun.jndi.rmi.object.trustURLCodebase` and `com.sun.jndi.ldap.object.trustURLCodebase`.
