Hello,
can you please provide the agent log (if it shows any errors) and/or rhe server log, as this sometimes also contains a stack trace when the configuration can't be loaded.

What infinite recursion do you mean?

Here is attached agent and server log. There is java.lang.StackOverflowError.
I've investigated rhq-jmx-plugin-1.1.0.GA in debug mode for dynamically changing of configuration. Target JMX Server was started in fresh tomcat 6.0.18. Sources of plugin has been taken from RHQ SVN.
JavaUtilLoggingResourceComponent.getLoggerLevel can't exit from recursive calls when LoggingMXBean.getParentLoggerName return zero string for a root loggers in hierarchies.
