Description bkramer 2017-01-13 15:30:41 UTC
This error is logged whenever user navigate to RHQ UI dashboard - in case it has Recent Events portlet or when user navigate to the resource's Summary tab that contains Resource: Events portlet. This error does not affect collection of events. 

Version-Release number of selected component (if applicable):
RHQ 4.12

How reproducible:
Always

Steps to Reproduce:
1. Install RHQ;
2. Import EAP server into RHQ inventory;
3. Enable events collection for imported EAP server;
4. Make sure that either RHQ Dashboard contains Recent Events portlet or resource's Summary page contains Resource: Events portlet;
5. Start to collect events;
6. Navigate to RHQ UI Dashboard or to EAP's Summary page;

Actual results:
For every collected event in the portlet a WARN message "Could not initialize private org.rhq.core.domain.event.EventSource org.rhq.core.domain.event.Event.source" will be logged in the server.log file;

Expected results:
No WARN messages are logged;

Additional info:

The server.log in DEBUG mode shows the following:

Additionally, when I double click on a event in the Event portlet, event data is properly shown.
