JBAS010153: Node identifier property is set to the default value

I got the following warning on startup of EAP 6.4.2:

WARN  [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 add a node-identifier attribute in the transactions subsystem. Here is my actual config after adding the attribute:

<subsystem xmlns="urn:jboss:domain:transactions:1.5">
  <core-environment node-identifier="eap6">
    <process-id>
      <uuid/>
    </process-id>
  </core-environment>
  <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
  <coordinator-environment default-timeout="300"/>
</subsystem>

The default standalone.xml has no node-identifier=”SOME_ID” entry and that’s the reason for this warning.
