Well, I searched again the whole code(after close() ), and is not too 
much code to search, I close only Consumers, Producers, Writers, 
OutputStreams, and the connection and browse on a shutdown hook. Maybe 
I'm wrong but I'm pretty sure I do I don't close the connection.
The strange thing is that is happened random, cannot figure out the 
conditions. Once it was at 3 minutes after I started the application, 
that was strange !!!
