Apache Tomcat, internal properties files

Is there a need to restart Apache Tomcat, if any of the internal properties files are modified or replaced?

 *   application.properties
 *   hibernate.properties
 *   restvalidation.json
 *   configuration.properties

First of all, do not replace these files from the backup. It may result in unstable application deployment.
Yes, restart the Tomcat service if there are any updates to the internal properties files above to make the changes effective.
