Java 6 upgrade -- ant replicating class files on compilation

Question

On upgradation to java 6 , ant seems to replicated class files
which have already been compiled into jars (which i have mentioned in classpath).
This is the ant script
<javac srcdir="src" destdir="/WEB-INF/classes" classpath="${library.jar}" deprecation="on" debug="true">
<classpath refid="library.classpath"/>
     <include name="com/test1/webapp/common/**/*.java"/>
</javac>
library.classpath contains path to library.jar
The above script works perfectly for java 5 but not for java 6.
The problem is that classes in the folder com/test1 are getting recompiled to WEB-INF/classes, when the classes were already in compiled to library.jar (which is in classpath).
Is there a solution to this problem?

Answer 1

This is the code that I have written:
public class Board extends JApplet
     JPanel p[][];
     public void init()
     try{
     SwingUtilities.invokeAndWait(new Runnable()
          public void run()
                    makeGUI(8,8);
     }catch(InterruptedException e){e.printStackTrace();}
     catch(InvocationTargetException e){e.printStackTrace();}
/* Board*/
private void makeGUI(int rows, int cols)
    p = new JPanel[rows][cols];
    Container contentPane = getContentPane();
    contentPane.setLayout(new GridLayout(rows, cols));
    for (int i = 0; i < rows; i++)
      for (int j = 0; j < cols; j++)
        p[i][j] = new JPanel();
        contentPane.add(p[i][j]);
        if (i % 2 == j % 2)
          p[i][j].setBackground(Color.white);
          else
          p[i][j].setBackground(Color.darkGray);
In this which one is inner class?
