Widlfly 8.2.0 – JBAS010153: Node identifier is set to the default value

In the latest version of Wildfly (8.2.0) there is a warning looking like

[org.jboss.as.txn] (ServerService Thread Pool -- 46) JBAS010153: Node identifier property is set to the default value. Please make sure it is unique.

To get rid of this you have to change the standalone.xml file.  Change this part

<subsystem xmlns="urn:jboss:domain:transactions:2.0">
  <core-environment>
    <process-id>
      <uuid/>
    </process-id>
  </core-environment>
  <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
</subsystem>

to look like this

<subsystem xmlns="urn:jboss:domain:transactions:2.0">
  <core-environment node-identifier="wildfly1">
    <process-id>
      <uuid/>
    </process-id>
  </core-environment>
  <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
</subsystem>

Of course you can use any value as identifier and “wildfly1” is just an example. Make sure not to use more than 23 characters.
