A VerifyError exception is thrown when next code is executed:

import java.util.ArrayList;
import java.util.List;

public class test
{
    public static void main(String[] args)
    {
        class X
        {
            private X[] EMPTY = new X[0];

            public X[] foo()
            {
                List<X> list = new ArrayList<X>();
                return list.size() == 0 ? EMPTY 
                                        : list.toArray(new X[list.size()]); 
            }
        };
        
        X x = new X();
    }
}

To workaround the problem, it is necessary to add (X[]) cast:
  return list.size() == 0 ? EMPTY : (X[])list.toArray(new X[list.size()]); 

Please note, that this only happens when the code is compiled within Eclipse. 
When the code is compiled by javac.exe from JDK 1.5 it does work correctly.
