         I would like to know what you mean by "String[0]". Does it mean it 
returns no pending message id?

         The behaviour of getPendingMessage() is like this: if the sending 
ack fails BUT it is still retrying, a sending thread still exists and 
getPendingMessage() would return its message id. However, if the sending ack 
fails for all retry, getPendingMessage() would return nothing because that 
ack message is marked SENT_FAILED in DB. Then, unregister() should be 
successful and should not report there is still pending message.
