This is not isolated but a repeated issue on the line mentioned. Do you have some suggestion for a patch?

Let me know if you need more information.

Environment:
Ubuntu Linux, Java-8, dedicated server.
List of mods in crash-report.

Also note that watchdog crashes don't give a good indication of the cause of the crash, they just print the current stack frame.

1.15 is not supported.

OK. Fair enough. Thanks for taking a look.
