Description Filip Brychta 2018-01-31 10:04:07 UTC 
Description of problem:
$Summary

Version-Release number of selected component (if applicable):
JON3.3.10

How reproducible:
Always

Steps to Reproduce:

Actual results:
in agent.log:
2018-01-31 04:58:04,044 ERROR [ResourceDiscoveryComponent.invoker.daemon-114] (org.rhq.plugins.agent.AgentDiscoveryComponent)- An error occurred while attempting to auto-discover the agent's own management interface

in server.log:
11:20:56,488 ERROR [org.rhq.enterprise.server.alert.engine.internal.AlertConditionCacheCoordinator] (EJB default - 3) Could not find agent for scheduleId = 24669

Expected results:
NPE should be fixed. Not sure if the error in server.log is expected

Additional info:
NPE in agent log is visible even when uninventoring platform without storage node.
Error in server.log was visible only once, it's not visible when doing uninventory second time.
Comment 1 Filip Brychta 2018-02-02 16:49:41 UTC 
The NPE is visible in JON 3.3.9 but the ERROR in server log is not -> it's a regression.

Comment 7 Prachi 2018-09-19 13:43:24 UTC 
Server log does not have any error, but in agent logs we can still see the error:

Comment 9 Michael Burman 2018-09-19 15:50:59 UTC 
That line number is from an old release, so either the agent wasn't updated or the build is missing something. Lines should be 136 & 79 for the first two items in the stack trace (133 is empty line in the current release/jon3.3.x)
Comment 10 Filip Brychta 2018-09-20 06:09:30 UTC 
Problem with co-located agent is that new plugins are not downloaded after upgrade until it's restarted or operation Update all plugins is manually executed.

When the agent has new plugins the issue is not visible -> marking as verified
