Java file does not receive parameters through InputStream

I have a problem with a class on my project application server. I need this class after compiled and running, get a message:

• or "MSG_PV" or "MSG_RV" from my REDMINE to publish projects
• or generate them, within my Repository.

The problem is that I deployed the Publish Project function now, whereas Generate was already running on my server. I have read on the net and in the documentation of JAVADOC that the InputStream method when used with readLine() , becomes InputStreamReader in Java 7.

How to proceed in this situation?

My code:

import java.net.*;
import java.io.*;
import java.util.Date;
import java.text.*;

public class server_versao extends Thread
{
   private ServerSocket serverSocket;
   private boolean server_is_busy  = false;

   public server_versao(int port) throws IOException
   {
      serverSocket = new ServerSocket(port);
   }

   private boolean execute_MSG_RV(String branch){
      try{
        if (Integer.parseInt(branch.substring(1,5)) >= 1308) //Versoes B1308 pra cima.
            return release_branch("release1308 " + branch);
        else
            return release_branch("release " + branch);
      }catch(Exception ex){
        return false;
      }
   }

   private boolean release_branch(String comando){
     boolean result = false;
     InputStream is;
     Process p;
     BufferedReader br;
     BufferedWriter bw;
     Date today;
     SimpleDateFormat ft;
     File f;
     FileWriter fw; 
     String aux, arch = "";

     try{
        today = new Date();
        ft = new SimpleDateFormat("dd.MM.yyy-hh.mm");
        f = new File ("logs/release/log-"+ft.format(today)+".txt");
        fw = new FileWriter(f);
        bw = new BufferedWriter(fw);
        System.out.println("Executando comando: "+ comando);
        p = Runtime.getRuntime().exec ("cmd /c gera_release.bat"+comando.toUpperCase());
        is = p.getInputStream(); 
        br = new BufferedReader (new InputStreamReader (is)); 
        aux = br.readLine(); 

        while (aux!=null){ 
            arch += aux + "\r\n";
            if (aux.contains("BUILD SUCCESSFUL") == true)
                result = true;
            aux = br.readLine();
        }

        bw.write(arch);
        bw.close();
        fw.close();
     }catch(Exception e){
        result = false;
     }
     return result;
   }

  private boolean execute_MSG_PV(String branch){
      try{
        if (Integer.parseInt(branch.substring(1,5)) >= 1308) //Versoes B1308 pra cima.
            return publish_version("publicar versoes_novas " + branch);
        else
            return publish_version("publicar versoes_antigas " + branch);
      }catch(Exception ex){
        return false;
      }
   }

   private boolean publish_version(String comando){
     boolean result = false;
     InputStream is;
     Process p;
     BufferedReader br;
     BufferedWriter bw;
     Date today;
     SimpleDateFormat ft;
     File f;
     FileWriter fw; 
     String aux, arch = "";

     try{
        today = new Date();
        ft = new SimpleDateFormat("dd.MM.yyy-hh.mm");
        f = new File ("logs/publish/log-"+ft.format(today)+".txt");
        fw = new FileWriter(f);
        bw = new BufferedWriter(fw);
        System.out.println("Executando comando: "+ comando);
        p = Runtime.getRuntime().exec ("cmd /c publicar_versao.bat"+comando.toUpperCase());
        is = p.getInputStream(); 
        br = new BufferedReader (new InputStreamReader (is)); 
        aux = br.readLine(); 

        while (aux!=null){ 
            arch += aux + "\r\n";
            if (aux.contains("BUILD SUCCESSFUL") == true)
                result = true;
            aux = br.readLine();
        }

        bw.write(arch);
        bw.close();
        fw.close();
     }catch(Exception e){
        result = false;
     }
     return result;
   }

   public void run()
   {
      boolean success = false;
      String msg;
      while(true)
      {
         try
         {
            System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "...");
            Socket server = serverSocket.accept();
            System.out.println("Just connected to " + server.getRemoteSocketAddress());
            DataInputStream in = new DataInputStream(server.getInputStreamReader());
            msg = in.readLine();
            if (msg.equals("MSG_RV"))
                success = execute_MSG_RV(in.readLine());
            else if(msg.equals("MSG_PV"))
                success = execute_MSG_PV(in.readLine());

            DataOutputStream out = new DataOutputStream(server.getOutputStream());
            if (success)
                out.writeUTF("MSG_SUC");
            else
                out.writeUTF("MSG_ERR");
            server.close();
         }catch(IOException e)
         {
            e.printStackTrace();
            break;
         }
      }
   }
   public static void main(String [] args)
   {
      int port = Integer.parseInt(args[0]);
      try
      {
         Thread t = new server_versao(port);
         t.start();
      }catch(IOException e)
      {
         e.printStackTrace();
      }
   }
}

When the file receives the parameters within this block:

DataInputStream in = new DataInputStream(server.getInputStreamReader()); 
msg = in.readLine(); 
if (msg.equals("MSG_RV")) 
    success = execute_MSG_RV(in.readLine()); 
else if(msg.equals("MSG_PV")) 
    success = execute_MSG_PV(in.readLine()); 

You should move to the function called what is inside in.readLine() and complete the rest of the calls. But I did a debug and it reads the data but does not process. There seems to be an error with my in.readline()
