I've created a test case for this issue: https://github.com/jvanheesch/hibernate-orm/commit/03a55c7fbff44613abc6c48cd4e942beb29d2750.

Additional information:

• Test case was based on another test case (https://hibernate.atlassian.net/browse/HHH-12985)
• I tried to extract this issue from a webapp, where I have similar entities, but I ended up with a different error message (webapp: org.hibernate.PropertyNotFoundException).
• Based on https://docs.jboss.org/hibernate/orm/5.1/userguide/html_single/chapters/domain/access.html, I believe the correct behavior should be as follows:
• MyEntity should have field access, because @Id annotation is placed on a field.
  This appears to work correctly (getTest() is not interpreted as a property, annotating MyEntity with @Access(AccessType.FIELD) does not change behavior).
• MyEmbeddable should inherit access strategy from its owning entity.
  This appears to work incorrectly, as I've found two workarounds for this issue:
• Annotate the MyEmbeddable class with @Access(AccessType.FIELD)
• Add getter & setter for description to MyEmbeddable.
  Sadly, both workarounds are unsatisfactory.
• Creating this test case took me way too long because of https://lists.jboss.org/pipermail/hibernate-dev/2017-October/016684.html, so maybe set-up can be improved?
