 Description   

If a TNT minecart explodes, the server will crash. Attempting to restart the server afterwards will cause the server to crash immediately after loading the world with the same error, rendering the world unusable until the TNT minecart is removed externally.

This crash occurs on a fresh Spigot server with no plugins or config changes. This issue does not occur on a vanilla 1.19.2 server.

I've attached 2 world files to help reproduce this issue. world-beforecrash includes the world shown in the screenshot - pull the lever to cause the TNT minecart to explode and crash the server. world-aftercrash is a copy of the world after causing the server to crash, where loading the world in a Spigot server will cause the server to crash on its own.

Opening a world that caused the Spigot server to crash in vanilla will simply have the minecarts explode.

Please let me know if there is any more information I can provide. Thank you!

Imo. the far better solution would be to make ExplosiveMinecart actually extend Explosive. Not sure why that functionality was never added.

The problem was is new beause recently there was a missing Event for the explode of the entity... 

They added this:

ExplosionPrimeEvent event = new ExplosionPrimeEvent((org.bukkit.entity.Explosive) this.getBukkitEntity(), (float) (4.0D + this.random.nextDouble() * 1.5D * d1), false);

But need to change it to this:
ExplosionPrimeEvent event = new ExplosionPrimeEvent(this.getBukkitEntity(), (float) (4.0D + this.random.nextDouble() * 1.5D * d1), false);
