Unable to modify poller packages through the Monitoring Locations UI

When testing the remote poller on latest snapshot of Meridian 2017.1.0, I found that it was not working.

The reason is that the Angular UI that manages the Monitoring Locations is not able to add poller packages to the server. I can see an error on FireBug:

XML Parsing Error: no root element found Location: http://192.168.205.187:8980/opennms/api/v2/monitoringLocations/RDU Line Number 1, Column 1:

If I go to the database, and add poller packages directly to the appropriate table and restart, for example:

insert into from monitoringlocationspollingpackages values ('RDU','raleigh');

The remote poller works without issues.

So, the problem seems to be a limitation of the UI.
