http://jira.hyperic.com/browse/HHQ-1928
The agent hangs during auto-discovery of HQ JBoss 4.0 when using the bundled JRE 1.4. This appears to be the result of an uncaught exception:
java.lang.UnsupportedClassVersionError: javax/management/MBeanException (Unsupported major.minor version 49.0)
at org.hyperic.hq.agent.server.CommandDispatcher.processRequest(CommandDispatcher.java:121)
at org.hyperic.hq.agent.server.CommandListener.listenLoop(CommandListener.java:191)
at org.hyperic.hq.agent.server.AgentDaemon.start(AgentDaemon.java:705)
at org.hyperic.hq.agent.server.AgentDaemon$RunnableAgent.run(AgentDaemon.java:769)
at org.hyperic.hq.agent.server.AgentDaemon.main(AgentDaemon.java:782)
The only work around is to remove the agent's bundled JRE 1.4 and set JAVA_HOME to a 1.5 jre.
