Petals ESB Container

The container remains stuck after an unusual usage.

1. Run the JConsole and onnect to brand new Petals through JMX (start Petals first).
2. Load a new installer for a component (e.g. the sample client). Petals is fine with this.
3. Invoke the same JMX operation with the same parameter (basially, clcik the button from the JConsole a second time). Peals displays an exception.
4. Try to invoke another JMX operation (e.g. startComponent). Nothing happens in the Petals console.
5. Try to shutdown Petals from the command line, by invoking the shutdown script. Nothing happens in the Petals console.
6. Try to copy a component in the install directory. Five minutes later, it is still here.

The container should handle this without remaining stuck.
It should still react, even if the user makes a mistake (in purpose or not is not the deal here).
