Description Ian Springer 2011-11-22 17:21:13 UTC 
This should never happen ...

Each of the DOWN resources has a Resource error like this:

org.rhq.core.clientapi.agent.PluginContainerException: Failed to start component for resource Resource[id=10166, type=Plugin Container, key=rhq.pc:type=PluginContainer, name=Agent Plugin Container, parent=RHQ Agent].

I'm thinking this may be a plugin container bug. Note, I ran the "plugins update" Agent prompt command a couple times prior to noticing this issue.

[master b33a340] - ensure resource classloader is initialized in processSyncInfo() prior to making any resource component facet calls.

QE, try running the "plugins update" Agent prompt command and then checking for Agent child resources being down or any other conspicuous availability-related problems.

Looks good in master.
