Placeholder ##DEFAULT_DATASOURCE## is not replaced during the container startup process

Environment

• JBoss EAP for OpenShift Container Platform
  • 7.3

Issue

If standalone-openshift.xml is brought from jboss-eap-7/eap71-openshift or jboss-eap-7/eap72-openshift to jboss-eap-7/eap73-openjdk8-openshift-rhel7, and even if the environment variable ENABLE_GENERATE_DEFAULT_DATASOURCE=true is set, then the following error occurs during starting the EAP7.3 container:

WARN You have set environment variables to configure the datasource in the default-bindings in the ee subsystem subsystem which conflicts with the value that already exists in the base configuration. The base configuration value will be used. Fix your configuration.

}

In this error occurs, the place holder ##DEFAULT_DATASOURCE## is not replaced during starting up the EAP 7.3 container.
