If one will try to define some metadata in a trait and then to override this metadata in the MappedSuperclass that uses the trait he will fail in the case properties were not set as private. The issue is described on StackOverflow https://stackoverflow.com/questions/46354858/override-association-mapping-of-a-trait-property-in-doctrine-2-6

I wrote the test case that succeeds on the attempt to override a private property and fails on the attempt to override a protected property. 367b11b86d

The root of the issue is in the AnnotationDriver's code:
53245e8a73/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php (L277-L286)
It skips all non-private properties for a MappedSuperclass and therefore they do not appear in its metadata definition.

When the driver tries to do the overriding:
53245e8a73/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php (L478)
He fails to find the overridden property in the metadata and throws an exception.
