+++ This bug was initially created as a clone of product Bug #858813 +++ Description of problem: Even when Augeas support is disabled, the agent reports the following warning for each Apache server and virtual host service in agent inventory: WARN [ConfigurationManager.threadpool-1] (rhq.core.pc.configuration.ConfigurationCheckExecutor)- Unable to check for updated configuration Version-Release number of selected component (if applicable): 3.0.1 How reproducible: Always Steps to Reproduce: 1. Install JON system * Change agent configuration property rhq.agent.plugins.configuration-discovery.period-secs to 120 seconds. 2. Install and start Apache Web Server (httpd) 3. Start JON system 4. Add Apache Web Server to inventory Actual results: The following warnings appear every at two minute intervals: 2012-09-19 10:40:17,613 INFO [ConfigurationManager.threadpool-1] (rhq.core.pc.configuration.ConfigurationCheckExecutor)- Starting configuration update check 2012-09-19 10:40:17,618 WARN [ConfigurationManager.threadpool-1] (rhq.core.pc.configuration.ConfigurationCheckExecutor)- Unable to check for updated configuration java.lang.IllegalStateException: Configuration and child resource creation/deletion support for Apache is optional.

Additional info: This is happening because the loadResourceConfiguration methods in ApacheServerComponent and ApacheVirtualHostServiceComponent are not implemented to handle a situation when configuration is disabled. Instead, the methods treat isAugeasEnabled = false as an error condition and throw and exception. This should not happen if the user has explicitly disabled Augeas and therefore configuration management for the Apache resource. According to the API doc for ConfigurationFacet.loadResourceConfiguration(), the methods should return null when configuration management is disabled by the plug-in. However, in this case, we are throwing an exception when configuration is disabled. I think the expected behavior here is to perhaps log a debug message when loadResourceConfiguration is returning null due to isAugeasEnabled returning false without an exception being raised and in cases where isAugeasEnabled throws an exception, we log this as a warning and still return null.
master commit bd8aa47cbe7d0f501efd6879b8928505d15d6a08 Author: Jay Shaughnessy <jshaughn> Date: Mon Feb 10 17:37:07 2014 -0500 - Applied Larry's recommended fix. Return null of augeas is disabled as per the jdoc of loadResourceConfiguration().
