Using Drupal 8.x (latest head) I cannot run "field types" tests. When I run them (from the UI) I get this error:
An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. Path: /repo8/drupal/batch?id=6&op=do_nojs&op=do StatusText: OK ResponseText: Fatal error: Cannot access protected property Drupal\field_test\Plugin\Core\Entity\TestEntity::$isDefaultRevision in /htdocs/repo8/drupal/core/lib/Drupal/Core/Database/StatementPrefetch.php on line 301
The problem happens with a fresh drupal installation with the standard profile set up to use a Sqlite database.
I am using Mac OS X Mountain Lion and I am running the testing UI using Safari and/or Google Chrome. My local PHP environment is "powered by" MAMP (latest version).
