From b44e80368f30993e543b9cd43097a5a41118e16f Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Sat, 22 Sep 2018 15:56:59 -0400 Subject: [PATCH] Catch JsonParseException in Entity and TE names As a result, data that no longer parses correctly will not crash the server instead just logging the exception and continuing (and in most cases should fix the data) Player data is fixed pretty much immediately but some block data (like Shulkers) may need to be changed in order for it to re-save properly No more crashing though. diff --git a/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java b/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java index e38a0d488e..a245df1dce 100644 --- a/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java +++ b/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java @@ -56,7 +56,7 @@ public abstract class CommandBlockListenerAbstract implements ICommandListener { this.g = nbttagcompound.getString("Command");
