From 72e93bc7a90780864ce743797ea17219c931500c 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 e6bf34ab00..c447cf1aed 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 b03316bc8c..5d31068d7d 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 670f8313ae..d49e210a3c 100644 --- a/src/main/java/net/minecraft/server/MCUtil.java +++ b/src/main/java/net/minecraft/server/MCUtil.java @@ -339,4 +339,19 @@ 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 21a2415fbe..7a911c5a5e 100644 --- a/src/main/java/net/minecraft/server/TileEntityBanner.java +++ b/src/main/java/net/minecraft/server/TileEntityBanner.java @@ -59,7 +59,7 @@ 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 } } -- 2.24.1
