While using springboot unable to start the process for redeployment without doing any changes in BPMN processes


We are using Spring Boot .

First time deployment working fine. if we do any changes in any bpmn file in the project and deploy it again also working fine.
If we changed only java or any external files (like .ftl or application.properties file change like that) without touching bpmn (means without doing any changes in modeler) and It is deployed fine and we are not seeing any log issue also and when we try to start the process, BPMN is received the request but not progressing after that (stuck with start activity only).
