Description

After a .config file is either deployed via the JcrInstaller or the FileInstaller with a primitive array type (e.g. with a upper case "I" character type code, https://sling.apache.org/documentation/bundles/configuration-installer-factory.html#configuration-files-config) it can no longer be updated. Even if afterwards the config file is modified the according config won't be updated.
The following exception can be found in the log
