Major Description
On a clean startup (the data directory is empty) everything works OK. However, when I restart Karaf (without cleaning out the data directory) I consistently get the following exception:
Exception in thread "JMX Connector Thread [service:jmx:rmi:///jndi/rmi://localhost:1099/karaf-root]" java.lang.RuntimeException: Could not start JMX connector server

I'm thinking there may be timing errors. Note that the exception is only logged to the console - not to the log file. Perhaps it occurs before the logging bundle is installed?
I haven't seen this in previous versions of Karaf (2.1.0 and 1.6.0) but I've also added and changed a lot of bundles in addition to upgrading to Karaf 2.1.2. Thus I don't know for sure if this is a problem specific to Karaf 2.1.2.
