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. ( 'System Settings > Documents and Media > Service > Maximum File Size' is already set to 0 by default)
4. Go to Content > Documents and Media, click the + icon in bottom right and select 'Basic Document'
5. Click 'Choose File' button and select a file.

Result: At this point a validation error message 'Please enter a file with a valid file size no larger than true.' appears in red below the file upload control and the user is not able to proceed.
