From 53100d2c99d2a53b62adb36f41a95f7ff63cbb42 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 7867122974..ef2a496eda 100644 --- a/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java +++ b/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java @@ -59,7 +59,7 @@ public abstract class CommandBlockListenerAbstract implements ICommandListener { this.command = nbttagcompound.getString("Command"); this.successCount = nbttagcompound.getInt("SuccessCount"); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.setName(IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName"))); + this.setName(MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound)); // Paper - Catch ParseException } if (nbttagcompound.hasKeyOfType("TrackOutput", 1)) { diff --git a/src/main/java/net/minecraft/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index 16c55a9fa0..4619f2c928 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -1679,7 +1679,7 @@ public abstract class Entity implements INamableTileEntity, ICommandListener, Ke this.Z(); this.setYawPitch(this.yaw, this.pitch); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.setCustomName(IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName"))); + this.setCustomName(MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound)); // Paper - Catch ParseException } this.setCustomNameVisible(nbttagcompound.getBoolean("CustomNameVisible")); diff --git a/src/main/java/net/minecraft/server/MCUtil.java b/src/main/java/net/minecraft/server/MCUtil.java index 2a22bc6f3e..3a482466ec 100644 --- a/src/main/java/net/minecraft/server/MCUtil.java +++ b/src/main/java/net/minecraft/server/MCUtil.java @@ -409,4 +409,19 @@ public final class MCUtil { return null; } } + + @Nullable + public static IChatBaseComponent getBaseComponentFromNbt(String key, NBTTagCompound compound) { + if (!compound.hasKey(key)) { + return null; + } + String string = compound.getString(key); + try { + return IChatBaseComponent.ChatSerializer.jsonToComponent(string); + } catch (com.google.gson.JsonParseException e) { + org.bukkit.Bukkit.getLogger().warning("Unable to parse " + key + " from " + compound +": " + e.getMessage()); + } + + return null; + } } diff --git a/src/main/java/net/minecraft/server/TileEntityBanner.java b/src/main/java/net/minecraft/server/TileEntityBanner.java index 93911a8251..d35604edb2 100644 --- a/src/main/java/net/minecraft/server/TileEntityBanner.java +++ b/src/main/java/net/minecraft/server/TileEntityBanner.java @@ -60,7 +60,7 @@ public class TileEntityBanner extends TileEntity implements INamableTileEntity { public void load(NBTTagCompound nbttagcompound) { super.load(nbttagcompound); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.a = IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName")); + this.a = MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound); // Paper - Catch ParseException } if (this.hasWorld()) { diff --git a/src/main/java/net/minecraft/server/TileEntityContainer.java b/src/main/java/net/minecraft/server/TileEntityContainer.java index 473ec2cbde..ab6b86e4e9 100644 --- a/src/main/java/net/minecraft/server/TileEntityContainer.java +++ b/src/main/java/net/minecraft/server/TileEntityContainer.java @@ -17,7 +17,7 @@ public abstract class TileEntityContainer extends TileEntity implements IInvento super.load(nbttagcompound); this.chestLock = ChestLock.b(nbttagcompound); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.customName = IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName")); + this.customName = MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound); // Paper - Catch ParseException } } -- 2.25.0.windows.1
