Starting the reader with a MessageId inside a batch: (11:0:3:151) with :

client.newReader()
         .topic(topic)
         .startMessageId(startMessageId)
         .startMessageIdInclusive()
         .loadConf(readerConf)
         .create();

the first message I read with reader.readNext() happens to be the one with messageId (11:0:3:0).

This is 2.5.0 related since my library relies on 2.4.2 works correctly.
