Try to use getStrings() instead.

[DenAbr]

I know it, but i need to use the same code in different versions

[games647]

That's impossible if the protocol changed from a string to a json component. If you read the Javadoc description of the method getChatComponents, you see that this method is only for 1.7+.

Retrieves a read/write structure for chat components in Minecraft 1.7.2. *

* This modifier will automatically marshall between WrappedChatComponent and the * internal Minecraft IChatBaseComponent.

Same for the class description.

Represents a chat component added in Minecraft 1.7.2

You can try to detect the server version and then use the methods the server supports. Example:

private boolean supportsJson;

public void sendMessage() {
    String message = ChatColor.DARK_RED + "Test";
    if (supportsJson) {
        WrappedChatComponent jsonComponent = WrappedChatComponent.fromText(message);
        //send packet using .getChatComponents()
    } else {
       //send packet using getStrings()
    }
}

Thanks. I thought that there is way to make more graceful solution. So than I continue to use the same method as you described.
