/**
 * This is to workaround an issue with Spring.
 * 
 * In spring, if you inject a Map into a contructor, it 
 * ALWAYS will call entrySet and copy the entries into a new
 * map (HashMap).    Thus, any "deferred" processing will happen
 * immediately.  Also, things like the Bus may not be completely
 * initialized.  
 * 
 * We'll mark some of our Spring things with this interface and 
 * allow the MapProvider to be injected.
