      Batch subsystem currently uses org.jboss.msc.service.ServiceController#getService to retrieve services. For instance, 

      BatchSubsystemDefinition and JobOperationStepHandler

      https://github.com/wildfly/wildfly/blob/main/batch-jberet/src/main/java/org/wildfly/extension/batch/jberet/deployment/JobOperationStepHandler.java#L72

      This method has been deprecated, with no direct replacement:

          /**
     * Get the service.
     *
     * @return the service
     * @throws IllegalStateException if the service is not available (i.e. it is not up)
     * @deprecated this method will be removed in a future release
     */
    @Deprecated
    Service<S> getService() throws IllegalStateException;

      In the chat discussion, it's recommended for each subsystem to maintain its own cache of desired services, similar to clustering in this PR.
