(BungeeCord Messaging Channel) The message received in the Channel, is different than the one sent

Question

I encountered this problem, sending from a Paper Server a message (containing the command to be executed as String) through this code:

ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.writeUTF(executor.getExecutable().replace("%player%",player.getName()));
System.out.println(executor.getExecutable().replace("%player%", player.getName()));
player.sendPluginMessage(plugin, "hqueue:inventory", out.toByteArray());

(executor.getExecutable() returns a Command as String)

Bungeecord receives these value when made a Println through this code:

    @EventHandler
    public void onPluginMessageReceived(PluginMessageEvent event) {
        System.out.println("Data received: " + new String(event.getData()) + " --r");
        if(!event.getTag().equals("hqueue:inventory")) return;
        System.out.println("Data received: " + new String(event.getData()));
        ProxyServer.getInstance().getPluginManager().dispatchCommand(ProxyServer.getInstance().getConsole(), new String(event.getData()));
    
    
    }

Println results:

11:04:29 [INFO] Data received:  §queue add Jaamin test --r
11:04:29 [INFO] Data received:  §queue add Jaamin test

(§ with some extras spaces shouldn't be there)

And rightly, the command is not executed as it does not exist in that form.

Fixed using this code to read:

if(!event.getTag().equals("hqueue:inventory")) return;
DataInputStream dataInputStream = new DataInputStream(new ByteArrayInputStream(event.getData()));
String command = "";
try {
    command = dataInputStream.readUTF();
} catch (IOException e) {
    e.printStackTrace();
}
ProxyServer.getInstance().getPluginManager().dispatchCommand(ProxyServer.getInstance().getConsole(), command);

And this one to write:

                ByteArrayOutputStream b = new ByteArrayOutputStream();
                DataOutputStream out = new DataOutputStream(b);
                try {
                    out.writeUTF(executor.getExecutable().replace("%player%", player.getName()));
                } catch(Exception e) {
                    e.printStackTrace();
                }

                player.sendPluginMessage(plugin, "hqueue:inventory", b.toByteArray());
