CLONE - Config XML with <interface ...><any-ipv4-address /></interface> + -Djava.net.preferIPv4Stack=false produces binding to ANY address (error) -------------------------------------------------------------------------------------------------------------------------------------------------- Key: WFCORE-361 URL: https://issues.jboss.org/browse/WFCORE-361 Project: WildFly Core Issue Type: Bug Components: Domain Management Reporter: Pavel Janousek Assignee: Brian Stansberry Fix For: 1.0.0.Beta1 The same situation is with every shipped and supported configuration/profile. As base for my explanation I'm using standalone.xml. Standalone.xml declares xmlns as: {code} <server xmlns="urn:jboss:domain:1.3"> {code} The real XSD file which defined elements is jboss-eap-6.0/docs/schema/jboss-as-config_1_3.xsd. The very common Linux system has implemented and enabled dualstack in these days. If we instruct AS instance to bind to +any+ IPv4 address via {code}<interface name="public"> <any-ipv4-address /> </interface>{code} The real result is to bind running AS instance to +any+ IP address, not only in IPv4 address space but in IPv6 too! With default setting (= -Djava.net.preferIPv4Stack=true), result is correct - it is bound to ANY IPv4 addresses only.
