Smack client delivery only empty (null) message

Hi everyone, I’m using the smack client.
I have a problem, my smack client only delivers a blank (empty, null) message to the user.
smack version: 4.1.5

Smack 4.1.5 is pretty old. I’d suggest updating to the latest release.

Without any kind of context (such as code snippets, expected behavior, logs) it is not easy to help you with this problem.
