> The InternalResourceManager is waiting for the termination of its scheduledExecutor.
> The PRHARedundancyProvider initializes its recoveryExecutor using the InternalResourceManager's scheduledExecutor:
> {noformat}
> recoveryExecutor = new OneTaskOnlyExecutor(resourceManager.getExecutor(),
> new OneTaskOnlyExecutor.ConflatedTaskListener() {
> public void taskDropped() {
> InternalResourceManager.getResourceObserver().recoveryConflated(region);
> }
> });
> {noformat}
> The scheduleRedundancyRecovery method schedules a RecoveryRunnable if necessary.
> If that task hasn't fired yet, the InternalResourceManager doesn't close, and the JVM stays up.
