> When trying to access a StringMonitor from jmx-console, I get a
> ClassCastException from
> javax.management.monitor.Monitor.getObservedObjects(). This is because the
> method incorrectly iterates over the keys of the observedObjects HashMap,
> rather than the values. The Exception is raised when the iterator.next() is
> cast to an ObservedObject, since the keys are ObjectNames. The following
> patch fixes the problem.
