Also on Fedora 36 Linux. And this (extra 't' and '//') has been troubling me for many years and many versions of Fedora. Is it really that hard to fix or do you just not care?

This bug still affects release 1.16.4 (vanilla client and server) using the following custom spawner:

/setblock ~ ~-1 ~ minecraft:spawner\{SpawnData:{id:iron_golem},SpawnCount:3,SpawnRange:4,RequiredPlayerRange:25,Delay:20,MinSpawnDelay:9600,MaxSpawnDelay:9600,MaxNearbyEntities:25} replace

Spamming the client logs with thousands of warnings about:

Exception loading entity: u: Loading entity NBT at aqa.f(SourceFile:1663) at aqe.a(SourceFile:473) at x.a(SourceFile:402) at aqe.a(SourceFile:472) at aqe.b(SourceFile:535) at aqe.a(SourceFile:516) at bqz.d(SourceFile:254) at ecp.a(SourceFile:22) at ecp.a(SourceFile:12) at ecd.a(SourceFile:107) at ecd.b(SourceFile:96) at ecd.a(SourceFile:128) at ecd.a(SourceFile:96) at eae.a(SourceFile:1260) at dzz.a(SourceFile:727) at dzz.a(SourceFile:546) at djz.e(SourceFile:1048) at djz.e(SourceFile:681) at net.minecraft.client.main.Main.main(SourceFile:215) Caused by: java.lang.ClassCastException: class dwt cannot be cast to class aag (dwt and aag are in unnamed module of loader 'app') at bai.a(SourceFile:170) at aqa.f(SourceFile:1654) ... 18 more

As a consequence, user logs can grow very large.

Confirmed for pre4. This comes up in lots of situations, particularly when making datapacks:

Example commands:

    /data get entity @p

and since I have a lot of scoreboard objectives: 🙂

    /scoreboard objectives list

 EDIT: Linux client and server. Java 8.
