205.

When a class has a field declaration that is an anonymous class and multiple 
constructors, we can get an ArrayIndexOutOfBoundsException.
Here is a test case to reproduce:

package p1;

import java.util.*;

public class A  {
	Object o1 = new Object() {
       public void foo() {
          Object o = A.this.bar();
          if(o !=null)
             o.toString();
       }
	  };
   public A()
   {
   }
   public A(TableModel aM)
   {
   }

    public A(int aNumRows, int aNumColumns)
   {
   }

    public A(Vector aRowData, Vector aColumnNames)
   {
   }

    public A(Object[][] aRowData, Object[][] aColumnNames)
   {

   }
   Object bar() { return null; }
}

This problem is fixed and the fix is released in HEAD.
The reason of the exception is that the local variable binding didn't reset its 
initialization count.
This was a side-effect of the fact that we regenerate multiple times the 
anonymous class. The field declaration is included in each constructor.
