Since the new logic uses addFirst() instead of simply add(), the last IPv4 address/network adapter gets the first in the resulting list. The as primary the method org.jacorb.orb.iiop.IIOPAddress.getLocalHost() uses the first address of this list (which is the last in the system). 3236 1 jacorb 2014-11-12 06:32:14 +0000 Can you run ifconfig to show your OS config and also run org.jacorb.util.Diagnostic ? 3237 2 jens 2014-11-12 07:14:29 +0000 ipconfig: ========= Windows IP Configuration Ethernet adapter Hausnetz: Connection-specific DNS Suffix . : mydomain.de IPv4 Address. . . . . . . . . . . : 10.49.4.111 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 10.49.4.1 Ethernet adapter VMware Network Adapter VMnet1: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::50f2:5478:714d:ae6f%14 IPv4 Address. . . . . . . . . . . : 192.168.42.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter VMware Network Adapter VMnet8: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::8166:4bd9:927c:cf6f%15 IPv4 Address. . . . . . . . . . . : 192.168.88.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter VirtualBox Host-Only Network: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::844c:5d4e:144f:868b%18 IPv4 Address. . . . . . . . . . . : 192.168.56.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : org.jacorb.util.Diagnostic: =========================== JacORB Version: JacORB V3.5 (www.jacorb.org) (C) The JacORB project 1997-2014 11 July 2014 with SHA 0620c4ad Operating system name: Windows 7 Operating system version: 6.1 Operating system architecture: amd64 Java Vendor: Oracle Corporation Java Version: 1.7.0_71 Runtime max memory: 2731M Found the following network addresses: /192.168.56.1 / mycomputer.mydomain.de /192.168.88.1 / mycomputer.mydomain.de /192.168.42.1 / mycomputer.mydomain.de /10.49.4.111 / mycomputer.mydomain.de /fe80:0:0:0:0:5efe:c0a8:3801%17 / fe80:0:0:0:0:5efe:c0a8:3801%17 /fe80:0:0:0:0:5efe:c0a8:5801%13 / fe80:0:0:0:0:5efe:c0a8:5801%13 /fe80:0:0:0:0:5efe:c0a8:2a01%12 / fe80:0:0:0:0:5efe:c0a8:2a01%12 /fe80:0:0:0:0:5efe:a31:46f%11 / fe80:0:0:0:0:5efe:a31:46f%11 /127.0.0.1 / 127.0.0.1 /0:0:0:0:0:0:0:1 / 0:0:0:0:0:0:0:1 /fe80:0:0:0:50f2:5478:714d:ae6f%14 / mycomputer.mydomain.de /fe80:0:0:0:8166:4bd9:927c:cf6f%15 / mycomputer.mydomain.de /fe80:0:0:0:844c:5d4e:144f:868b%18 / mycomputer.mydomain.de Preferred non-loopback address /192.168.56.1 Default locale en_US (which is English (United States)) System file encoding property: Cp1252 Cannonical encoding: Cp1252 Default WChar encoding: UTF16 INFO Initialising ORB with ID: WARNING Warning - unknown codeset (Cp1252) - defaulting to ISO-8859-1 INFO InterceptorManager started with 0 Server Interceptors, 0 Client Interceptors and 1 IOR Interceptors Created ORB org.jacorb.orb.ORB =========================== As you can see: the order of adapters is reversed and the main issue for me: the primary/preferred IP address becomes a virtual network adapter resulting is corba objects bound to this wrong/internal address. 3246 3 jacorb 2014-12-03 03:43:09 +0000 Fixed by SHA 74373300a84ad72e32cc920d2d4eab28db90f88c Thanks to Jens for lots of help debugging and running multiple custom builds to test the fix!
