As reported in https://github.com/tigase/tigase-server/issues/116:

Describe the bug A problem has emerged while upgrading to a new version of smack, it seems that the client sends the end of stream </stream:stream> but the server did not sends it back Full discussion with network traffic here: https://discourse.igniterealtime.org/t/smack-timeout-during-disconnect/90651/5

To Reproduce Steps to reproduce the behavior: Just disconnect with one of the latest version of smack or any other client

Impact Smack waits for end of streams from the server and wait until a timeout expires

Expected behavior The server should sends the end of the stream so the client know that all packets has been processed correctly
