Steps to reproduce:

1. Start Liferay, log in as Admin
2. Go to Content > Froms > Data Providers
3. Create a new Data Provider eg: Countries of the World
4. Create a new form and add a Select from List field
5. Under the Create List option select From Data Provider
6. Select your new Data Provider and its output parameter
7. Go to the Site
8. Put a Forms portlet on the page
9. Select your new form to display
10. Check the localhost_access_log in your tomcat_home\logs folder

Note: because the issue is intermittent it might be needed to repeat the steps several times. Simulate a high load on the server might make it easier to reproduce.

Actual behavior: You will see that the Rest Api is called twice: 127.0.0.1 - - [20/May/2020:16:02:05 +0000] "GET /api/jsonws/group/get-user-sites-groups-count HTTP/1.1" 200 1
Expected behavior: The Rest Api should be called only once.
