The variables are not the same for some reason.

Here is where I receive the object:
1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
13  
14  
         if(omsg instanceof ServerPlayerStateMessage){
            ServerPlayerStateMessage msg = (ServerPlayerStateMessage) omsg;
            for(int i=0; i<msg.players.length; i++){
               PlayerModel newModel = msg.players[i];

               PlayerModel oldModel = playerManager.getByID(newModel.clientID);
               
               
               if(oldModel != null){
                  oldModel.setTilePos(newModel.tileX,newModel.tileY);
               }

            }
         }


Here is where I send:
1  
2  
3  
4  
5  
6  
7  
            if(msg instanceof ClientMoveMessage){
               System.out.println("Client move msg");
               
               ClientMoveMessage msg2 = (ClientMoveMessage) msg;
               
               cThread1.getPlayerModel().setTilePos(msg2.tileX, msg2.tileY);
            }

   public void sendPlayerStates(){
      ArrayList<PlayerModel> playerModels = new ArrayList<PlayerModel>();
     
      for(int i=0; i<cThreads.size(); i++){
         ClientThread t = cThreads.get(i);
         playerModels.add(t.getPlayerModel());
      }
     
         
      ServerPlayerStateMessage msg = new ServerPlayerStateMessage();
     
      msg.players = new PlayerModel[playerModels.size()];
     
      msg.players = playerModels.toArray(msg.players);
     
      broadcast(msg);
         
   }


Here is the actual objectoutputstream writing:

   public void sendAll() {
      if(socket.isConnected()){
         Object msg = null;
         while((msg = outQueue.poll()) != null){
            try {
               out.writeUnshared(msg);
               out.flush();
               out.reset();
            } catch (IOException e) {
               // TODO Auto-generated catch block
              e.printStackTrace();
            }
         }
      }
   }

  public int clientID;
   public int tileX;
   public int tileY;
   
   public void setTilePos(int tileX, int tileY){
      this.tileX = tileX;
      this.tileY = tileY;
   }
   
}

I bet it's a protocol mistake.

Maybe it's a logical problem and oldModel is actually null, you should add asserts or debugging print statements.

okay as I was writing this message I found the error. My objectoutputstream thread for writing had 2 class files because I moved it at some point. I made the modification to reset the stream to the wrong file! Darn
