    [ https://issues.jboss.org/browse/AS7-648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12601991#comment-12601991 ] 

Scott Stark commented on AS7-648:
---------------------------------

Mark Little indicated that the initDefaultProcess in the com.arjuna.ats.arjuna.utils.Utility class is where the Uid implementation is chosen. That method queries the com.arjuna.ats.arjuna.common.CoreEnvironmentBean.getProcessImplementation:

    /**
     * Returns the class name of the Process implementation to use.
     *
     * Default: "com.arjuna.ats.internal.arjuna.utils.SocketProcessId"
     * Equivalent deprecated property: com.arjuna.ats.internal.arjuna.utils.processImplementation
     *
     * @return the name of a class implemeting Process.
     */
    public String getProcessImplementation()
    {
        return processImplementation;
    }

The proper way to implement this would be to add a processImplementation attribute to the org.jboss.as.txn.TransactionSubsystemProviders as7 integration layer's parsing of the urn:jboss:domain:transactions:1.0/core-environment, for example something based on the jdk uuids:

        <subsystem xmlns="urn:jboss:domain:transactions:1.0">
            <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
            <core-environment socket-binding="txn-socket-process-id"
               process-implementation="java-uuid" />
        </subsystem>

> I'm seeing an attempt to bind an anonymous socket to localhost/127.0.0.1 even when the standalone.xml configuration has specified a loopback-address other than localhost/127.0.0.1 as the default:
>     <interfaces>
>         <interface name="default">
>             <loopback-address value="127.0.250.1"/>
>         </interface>
> The port is also not one listed in the socket-binding-group section. Both the interface and port should be coming from the server configuration.
> Thread attempting bind call:
> Socket[addr=localhost/127.0.0.1,port=0,localport=52394]
