Bug 499308

Description Melina Mongiovi 2016-08-06 14:22:38 EDT

Reproducing the bug:

Consider the following program:
package test1;
public class Test1 {
  public void methodToMove(){}
  private TestTarget target;
  public TestTarget getTestTarget(){
    return target;
  }
}

package test1;
public class TestTarget {
}

package test2;
import test1.Test1;
public class Test2 {
  public Test2(){
    new Test1().methodToMove();
  }
}

Now, let's move method Test1.methodToMove to TestTarget

Resulting program:

package test1;
public class Test1 {
  public TestTarget target;
  public TestTarget getTestTarget(){
    return target;
  }
}

package test1;
public class TestTarget {
 public void methodToMove(){}
}

package test2;
import test1.Test1;
public class Test2 {
  public Test2(){
    new Test1().target.methodToMove();
  }
}

This transformations changes the program behavior. Notice that, only in the resulting program, the Test2 constructor throws a Null Pointer.
