[MC-45838] Certain chat messages exceed 32767 byte limit and disconnect clients

I am on my minecraft server and I sometimes am curious what entities are around. I type in "/say @e" and the server kicks everyone out but does show in the server log the entities.

Steps to reproduce:

Start a server
Span some hundred entities
Issue /say @e

Code analysis by @unknown can be found in this comment.

Are you actually running the server on the latest snapshot or is the server running a snapshot prior to 14w04b?

Avery Barley 2014-01-24T21:42:51Z

I am running it in 14w04b and it just crashes when I type the code in

kumasasa 2014-01-25T00:21:16Z

Confirmed (it doesn't crash but kicks the player)

Confirmed for 1.8pre2

StevenNL2000 2014-11-26T17:27:47Z

The description of this bug is actually incorrect, because /say @e is not broken. The reason it kicks you is that there are so many entities that the text becomes too long to display in one chat message. Anything with an output of varying length could technically cause this. That's why it would be better to change the description of this bug to "Messages of more than 32767 characters kick the player".

kasamikona 2014-12-24T21:48:43Z

A more appropriate title/description would be "Certain chat messages exceed 32767 character limit and disconnect clients."

Summary should be changed to "Certain chat messages exceed 32767 byte limit", because the data needs to be 32767 bytes, not characters.

Please link to this comment in the description

The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.

The problem is that the server is sending invalid packets. The method net.minecraft.network.NettyPacketEncoder.encode(ChannelHandlerContext, Packet<?>, ByteBuf) fails writing the packet data to the PacketBuffer, it prints the error message (in this case "String too big (was [X] bytes encoded, max 32767)") but sends the packet anyways. The packet contains now only the packet id. When the client tries to read the String from the packet it fails. I do not know how to prevent the server from sending the packet, however the client can probably catch exceptions which are thrown when the method net.minecraft.network.NettyPacketDecoder.decode(ChannelHandlerContext, ByteBuf, List<Object>) calls the method net.minecraft.network.Packet.readPacketData(PacketBuffer) and not add the packet to this list (which might contain read packets).

protected void decode(ChannelHandlerContext p_decode_1_, ByteBuf p_decode_2_, List<Object> p_decode_3_) throws IOException, InstantiationException, IllegalAccessException, Exception
{
    if (p_decode_2_.readableBytes() != 0)
    {
        PacketBuffer packetbuffer = new PacketBuffer(p_decode_2_);
        int i = packetbuffer.readVarIntFromBuffer();
        Packet<?> packet = ((EnumConnectionState)p_decode_1_.channel().attr(NetworkManager.attrKeyConnectionState).get()).getPacket(this.direction, i);

        if (packet == null)
        {
            throw new IOException("Bad packet id " + i);
        }
