Is there a publicly available issue tracker system to search for bugs and submit enhancement requests?
Yes. If you would like to search for a bug, report a bug, or submit an enhancement request for one of the core subsystems (i.e. the Server, the Agent or one of the core RHQ plugins), then use the RHQ JIRA located at http://jira.rhq-project.org/browse/RHQ. If your request is for one of the JBoss middleware plugins (or, more generally, a plugin provided by the Jopr project), then use the Jopr JIRA located at https://jira.jboss.org/jira/browse/JOPR. Please do not submit duplicate issues in both JIRAs – it won’t make us fix it any faster : ).
