> The new factory filters are supplementing the existing `jdk.jndi.object.factoriesFilter` global factories filter to determine if a specific object factory is permitted to instantiate objects for the given protocol.

> - Implementation for two new system and security properties have been added to the `com.sun.naming.internal.ObjectFactoriesFilter` class
> - `java.security` and `module-info.java` files have been updated with a documentation for the new properties
> - To keep API of `javax.naming.spi.NamingManager` and `javax.naming.spi.DirectoryManager` classes unmodified a new internal `com.sun.naming.internal.NamingManagerHelper` class has been introduced. All  `getObjectInstance` calls have been updated to use the new helper class.

> - `NamingManager.getObjectInstance` -> `NamingManagerHelper.getObjectInstance`. Methods responsible for setting/getting object factory builder were moved to the `NamingManagerHelper` class too.

> ### Test changes
> New tests have been added for checking that new factory filters can be used to restrict reconstruction of Java objects from LDAP and RMI contexts:

> - RMI protocol specific test: test/jdk/com/sun/jndi/rmi/registry/objects/RmiFactoriesFilterTest.java
> Existing `test/jdk/javax/naming/module/RunBasic.java` test has been updated to allow test-specific factories filter used to reconstruct objects from the test LDAP server. 
> 
> ### Testing
> tier1-tier3 and JNDI regression/JCK tests not showing any failures related to this change.
> No failures observed for the modified regression tests.
