FULL PRODUCT VERSION :
java version 1.8.0_60
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
 3.18.9-hardened #2 SMP Wed Jun 3 16:59:24 PDT 2015 x86_64 Intel(R) Pentium(R) CPU G3440 @ 3.30GHz GenuineIntel GNU/Linux


A DESCRIPTION OF THE PROBLEM :
On Linux, calls to java.net.NetworkInterface.getNetworkInterfaces do not return any interfaces which have no address or only an ipv6 link-local address configured.

On Windows, calls to the same function return all network interfaces, regardless of what kinds of addresses are configured.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
call java.net.NetworkInterface.getNetworkInterfaces and compare the returned values to the interfaces installed in the system.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Ideally I would expect it to return all network interfaces on the system, regardless of configuration state, like it does on Windows.

ACTUAL -
Windows returns all interfaces while Linux returns only interfaces with a configured IPv4 address.  (Note:  I didn't actually test with an IPv6 address other than link-local, but I can't think of a good reason to be ignoring link-local addresses specifically, and that's still not the behaviour presented on the other platform anyway)

REPRODUCIBILITY :
This bug can be reproduced always.

        while (netInterfaces.hasMoreElements()) {
            NetworkInterface iface = netInterfaces.nextElement();
            System.out.println("NIC " + iface.getName() + "\n");
        }
