Server crash - Ticking world entities

18w30a server crashes with "Stack Overflow" message. Crash log indicates an "out of bounds exception" while ticking world entities. This is just by wandering around in my base.

I attached two crash reports with very similar (probably the same) problem. (

I can also add to that that it happened for example when a Creeper was exploding underground. This is a case of running a multiplayer server on Java 10 

 

I also added

which seems as a different error caused by same thing.

I can confirm for my singleplayer worlds.

Confirmed SMP. Rolling back to 1.13.0 until this (or MC-134816) notes a fix.
