Java 9 中的 com.sun.jndi.dns.DnsContextFactory 是否有替换？

Question

下面是简单的代码：

Hashtable<String, String> env = new Hashtable();
env.put( "java.naming.factory.initial", "com.sun.jndi.dns.DnsContextFactory" );
DirContext dns = new InitialDirContext( env );

在Java9中产生以下异常。目前我使用9-ea+164-jigsaw-nightly。

javax.naming.NoInitialContextException: Cannot instantiate class:
com.sun.jndi.dns.DnsContextFactory [Root exception is java.lang.IllegalAccessException:
class javax.naming.spi.NamingManager (in module java.naming) cannot access
class com.sun.jndi.dns.DnsContextFactory (in module jdk.naming.dns) because module jdk.naming.dns
does not export com.sun.jndi.dns to module java.naming]

我检查了 jdk-9+168，但没有发现这个问题。你在最近的版本中看到它了吗？
