In case users change runtime strategy in deployment descriptor (to not be default - singleton) and build and deploy in workbench, provisioning to kie server (via controller) might override that strategy due to the way how container spec is created by the build and deploy executor:
https://github.com/kiegroup/kie-wb-common/blob/master/kie-wb-common-screens/kie-wb-common-project-editor/kie-wb-common-project-editor-client/src/main/java/org/kie/workbench/common/screens/projecteditor/client/build/BuildExecutor.java#L387

process config needs to be build in sync with what deployment descriptor provides, if exists.
