mac check in EAX failed about ts3j HOT 3 OPEN

I've connected TS3j to a 3.12.1 on Linux server without issue; that server is watchtower'd and auto-updates on Docker. I'm wondering if there is a compatibility issue here. Is the behavior any different if you don't set a client version string? To start with, I figure we can begin by ruling out any version-specific behavior.

If I connect to an empty server in version 3.12.1 on Linux everything works, and if I connect to ts3.black (200+ users online) I get this error.

Given the user count, this seems a lot like a similar problem I found with compression in #12. Maybe the cryptography routines suffer from similar "large" packet bugs? Looking at your logs more closely, your packet ID's jump by 3 ID's or more semi-regularly... that's really odd. Granted, you could be dealing with out-of-order delivery and/or packet loss, but I'm seeing:

(Did you remove those from your logs? If so, did those de-crypt OK?)

I'll have to take a deeper dive, specifically into the server you're on. When do the errors start? Is it at a specific point in the packet stream? Some of any "healthy" traffic you have would be helpful.
