Subject: BookKeeper newbie question

Hi,

I am experimenting with BookKeeper and have a question on LedgerHandler class. 
The readEntries(firstEntry, lastEntry) method takes the indexes of first and 
last entries. Also, the LedgerSequence object returned has method 
hasMoreElements().

Question:
1. How does a client knows the index of the last entry? I was expecting clients 
to make a call like readEntries(0, Integer.MAX_INT) and the hasMoreElements() to 

return false the moment there are no more entries. Am I missing something in the 

way the API is supposed to be used?

2. The LedgerSequence.hasMoreElements() returns true (even if there are no more 
entries), and the nextEntry returns null.

Can someone  please clarify the correct semantics of these APIs.
