Steps to reproduce:
1. Login to Liferay as administrator
2. Navigate to Control Panel > Configuration > System Settings > Infrastructure > Upload Servlet Request
3. Change 'Overall Maximum Upload Request Size' to 0 and save.
Actual result: the default value 104857600 is displayed, although the value 0 is saved in the configuration_ table and it is the actual value in effect
Expected result: the value 0 should be displayed

This behavior only occurs if the value is set to 0. For all other values, it will shown on the display.
