JBoss does not detect new directories in modules

Issue

In order to handle properties file in my application I applied the solution https://access.redhat.com/knowledge/solutions/122883
It works correctly but it doesn't handle the update of folders:
- A file "properties.index" is generated in the same directory than the properties folder containing all folders in the properties dir.
- once it has been generated this file is never updated.
- so that if I add a new folder containing properties file it will never appears in the "properties.index" and then

Thread.currentThread().getContextClassLoader().getResource("newDir/my.properties");

will never work
