[GitHub] [pulsar] PatrykWitkowski commented on issue #10483: Reader does not return any message when configured with reading inclusive latest messageId

   If you invoke `reader.hasMessageAvailable()` before `reader.readNext()` then it works as expected.
   It looks like in that case during searching if there're any messages available a message id for the last message is found and the reader pointer is set for it.
   Logs:
   ```
   17:14:42.290 [] [pulsar-client-io-1-1] INFO Get topic last message Id
   17:14:42.290 [] [pulsar-client-io-1-1] INFO Successfully getLastMessageId 150:0
   17:14:42.293 [] [pulsar-client-io-1-1] INFO Seek subscription to message id 150:0:-1
   17:14:42.308 [] [pulsar-client-io-1-1] INFO Successfully reset subscription to message id 150:0:-1
   ```
   
   You can use it as a **workaround**, but still this issue should be fixed.
