Crash
We were in the middle of a raid and the server crashed. This is possibly related to MC-155345, but I'm not sure anyone "left" the raid.
I've attached crash-2019-06-29_12.31.20-server.txt which was generated.
And here is the relevant section from latest.log:

The JVM also created its own log of the crash as hs_err_pid20640.log, which I've attached.
It also created a rather large java.core file, but it's 12GB and I'm not sure how I'd provide that to you. The problem is very repeatable, it happens every time I start the server, log in, and do much of anything. There's a ravager running about and I did strike it with a sword, which perhaps triggered the end of the raid, triggering the bug? I'll keep testing but it takes a long time when it creates the core file.
