Crash on update of an Entity

[neo-expert]

The following test case crashes:

 @Test
   public void shouldDetectRayIntersection() {
      // Given
      AABBTree<TestEntity> tree = givenTree();
      Rayf ray = new Rayf(0.0f, 0.0f, 0.0f, 1.0f, 1.0f, 0.0f);
      TestEntity entity1 = new TestEntity(1, 2.0f, 0.0f, 3.0f, 3.0f);
      TestEntity entity2 = new TestEntity(2, -5.0f, 0.0f, 3.0f, 2.0f);
      tree.add(entity1);
      tree.add(entity2);

      // When
      List<TestEntity> intersecting = new ArrayList<>();
      tree.detectRayIntersection(ray, intersecting);

      tree.update(entity1);
      tree.update(entity2);
      tree.update(entity2);
      tree.update(entity2);

      // Then
      assertEquals(1, intersecting.size());
      assertEquals(1L, intersecting.get(0).getID());
   }

Did you managed to fix this?
