So, this is some of the code that I added to Hierarchy:
/**
Requests that a configuration changed event be sent to any registered
{@link LoggerRepositoryEventListener}.
@since 1.3*/
public void fireConfigurationChangedEvent() {
if(repositoryEventListeners != null) {
int size = repositoryEventListeners.size();
LoggerRepositoryEventListener listener;
for(int i = 0; i < size; i++) {
listener = (LoggerRepositoryEventListener)
repositoryEventListeners.elementAt(i);
listener.configurationChangedEvent(this);
}
}
}
But there are also methods that allow one to remove a given listener from
the hierarchy. So, there will be a problem here if a listener is removed
while in the for loop to reportiting an event.
What would be the best way to deal with it? Just add a catch for the index
out of bounds exception or to synchronize on the listener vectors?
