> Essentially, an uninitialized PersistentMap loses the first put() into it if defined as non-extra-lazy.  
> The underlying cause is the code in PersistentMap#put() which attempts to readElementByIndex().  In the case of non-extra-lazy, readElementByIndex() returns the UNKNOWN marker object which is supposed to be used to signal that the delegate map is now initialized and to read the element directly from the map.  Long story short, PersistentMap#put() does not properly check the return value from readElementByIndex() and react accordingly.
