主 题：Re: RFR (XS) 8237806: Convert TIMEOUT of
sun.net.dns.ResolverConfigurationImpl into property

Hi Alan,
In our production environment, the content of /etc/resolv.conf may be
modified because of some reason, and we found that JVM can't know it when it
running.
There are some ways to fix this problem, one way is Adding
-Dsun.net.spi.nameservice.provider.1=dns,sun to enable
sun.net.dns.ResolverConfigurationImpl, but
the TIMEOUT value is too long for us, so we hope to use a system property to
control it.
If I read this correctly, you are running with
-Dsun.net.spi.nameservice.provider.1=dns,sun so that InetAddress is using the
DNS-only name service provider (based on JNDI-DNS), is that correct? Just
checking because that mechanism was removed in JDK 9, maybe you are proposing
this for jdk8u?
