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.
