I ran Etsy's Phan (static analyzer) on Drupal 8 and am investigating the output. It pointed out that Form API's callback_batch_operation is using $this when not in an object context.

ps: if this is confirmed as a bug. Then this code is probably not under tests. I must admit that I'm not sure what callback_batch_operation exactly does, but if nobody is using it (nobody reported any problems before) maybe we should just delete the code instead of fixing it.

Thanks Jeroen. So it's example code, that explains a lot :-)

Nevertheless the example is wrong. I just found out that Drupal::entityManager() is deprecated so I adjusted the patch.

@tvlooy: *.api.php files are examples on how to use the api. Those files are not executed or tested.

The example was wrong and your patch fixes it.
