A DESCRIPTION OF THE PROBLEM :
Given a NetworkInterface on a Solaris host which has subinterfaces defined on it, if we then obtain an enumeration of those sub-interfaces, then the following code throws an UnknownHostException:

try {
    Enumeration intfs = NetworkInterface.getNetworkInterfaces() ;
    while (intfs != null && intfs.hasMoreElements()) {
        NetworkInterface intf = (NetworkInterface) intfs.nextElement() ;
  Enumeration<NetworkInterface> subInterfaces = intf.getSubInterfaces() ;
while (subInterfaces != null && subInterfaces.hasMoreElements()) {
Enumeration<InetAddress> subInetAddresses = subInterface.getInetAddresses() ;
            while (subInetAddresses != null && subInetAddresses.hasMoreElements()) {
  InetAddress inetAddress = (InetAddress) subInetAddresses.nextElement() ;
boolean ipv6 = inetAddress instanceof Inet6Address;
if (ipv6) {
try {
                        // inet6Address should equal reversal
String reversalString = inet6Address.getHostAddress();
InetAddress reversal = InetAddress.getByName(reversalString) ;
                    } catch(UnknownHostException uhe) {
                          // UnknownHostException occurs here
                    }
                }
}
        }
    }
}

In other words, when dealing with an IPv6 InetAddress obtained from a sub-interface on Solaris 11 (when the sub-interface is virtual), calling InetAddress.getHostByName() to generate a string representation of the name, followed by a call to IentAddress.getByName() to generate an InetAddress from the string representation results in an UnknownHostException.

This happens on JDK8, but not on JDK7 nor JDK 6.

REGRESSION. Last worked in version 7u79

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test program provided below on a Solaris 11 Sparc host with virtual interfaces defined.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The results expected are the same as the Actual Result below, except that there should be no problem doing the "reverse lookup" on the InetAddress; in other words, we should be able to take an Inet6Address, create a String representation, and then return to the Inet6Address using the String representation and the method getByName.
ACTUAL -
Here are the results in which the exception occurs:
