• WARN message "Discovered multiple resources with resource key [deployment=HelloWorld.jar]. This is not allowed and they will be removed from discovery..." in the agent.log file
• My agent.log file shows the following WARN message:

2016-02-15 15:55:52,345 WARN  [ResourceDiscoveryComponent.invoker.daemon-1] (rhq.modules.plugins.jbossas7.VersionedSubsystemDiscovery)- Discovered multiple resources with resource key [deployment=sipap.jar].  This is not allowed and they will be removed from discovery.  This is typically caused by having multiple versions of the same Deployment deployed.  To solve the problem either remove all but one version of the problem deployment or disable versioned deployment handling by setting -Drhq.as7.VersionedSubsystemDiscovery.pattern=disable for the agent.
