Steps To Reproduce:

Test case:
  public class A {
    public static void main(String[] args) {
      new Thread() {
        public void run() {
          System.out.println(23);
	}
      }.start();
    }
  }

  class MyThread {
    public void start() {
      System.out.println(42);
    }
  }

Renaming class "MyThread" to "Thread" shadows the library class java.lang.Thread, which is not noticed by Eclipse. Thus the program changes from printing "23" before refactoring to printing "42" after.
