JGroups throws UnknownHostException on processing IPv6 zone interface id with a subinterface

    XMLWordPrintable

Details

    • Release Notes
    • Hide
      This issue is caused by a regression in JDK 8 (see bug JDK-8168840), in which IPv6 addresses associated with virtual interfaces on Solaris 11 are not handled correctly. Such addresses were handled correctly in previous JDK versions. The issue can be avoided by either avoiding the use of virtual interfaces on Solaris 11, or by using an earlier version of the JDK which handles the addresses correctly.

    Description

      JGroups pick up IPv6 zone id index and it fails at translating it into an interface name:

      Address

      • address used 2620:52:0:105f:0:0:ffff:188%net0:2
      • Caused by: java.net.UnknownHostException: no such interface net0:2

      WDYT? Why should JGroups even try to do that?
