CLI commands that update domain.xml file delete the XML comments

Issue

• When running any CLI command that updates the file domain.xml, like deployment of an application, the updated file has all the commented out line deleted.
  How can I avoid this?

Below is the sequence of steps:

1. Stop all EAP processes
2. Add comments and comment out some lines in domain.xml file
3. Start EAP
4. Start CLI
5. Deploy app (.war file) or run any other CLI command that would update domain.xml
6. Check domain.xml file --> all comments and commented out lines have been removed
