Description of problem:
When a web application is clustered, RHQ is unable to collect metrics like the number of active sessions.
This is due to an inconsistency in the property names returned from the AS's profile service that returns lowercase names when the web app context is not clustered (e.g. "activeSessions") but when it is clustered the property names start with an uppercase letter (e.g. "ActiveSessions").
This has been filed as a bug in the EAP:
However, RHQ should be robust enough to handle such differences.
Version-Release number of selected component (if applicable):
as5 plugin in all versions
Steps to Reproduce:
1. Start JBoss AS 5 or up in the "all" profile (so that clustering is enabled)
2. Deploy the attached test WAR.
3. Wait for some metrics to be collected
Active Sessions and other metrics are never collected
All metrics are collected according to their schedules
