• Git Pull Request: https://github.com/Ithildir/liferay-portal/pull/508

Steps to reproduce:

1. Navigate to Configuration > System Settings
2. Click on any module with a multi-value setting in its configuration
   • Examples: Web Content, Web Content Administration, Documents & Media Service, Elasticsearch
3. Save the default settings
4. Export configuration for module

Result: Multi-value settings are in separate lines in the *.cfg file. Only the first value (the value in the same line as the key) is read.

##
## To apply the configuration, place this file in the Liferay installation's osgi/modules folder. Make sure it is named com.liferay.journal.configuration.JournalServiceConfiguration.cfg.

Proposed solution: Exporting all System Config entries as *.config instead of *.cfg
