In this release, the JDK implementation of the LDAP provider no longer supports deserialization of Java objects by default:

* The default value of the `com.sun.jndi.ldap.object.trustSerialData` system property has been updated to `false`.

The transparent deserialization of Java objects from an LDAP context will now require an explicit opt-in. Applications that rely on reconstruction of Java objects or RMI stubs from the LDAP attributes would need to set the `com.sun.jndi.ldap.object.trustSerialData` system property to `true`.
