@PostLoad hook being executed more than once for the same entity when loaded through relationship

Scenario:

• Entity mapping: A manytomany B
• Hooks: a @PostLoad hook on B
• Persisted entities: two instances of A related to the same instance of B

When I load both A's using the EntityManager, and access the instance of B (internally from each A), the @PostLoad hook is being triggered twice instead of once (as there is only one instance of A).

I left an attachment with the code ready to run (please read the README.md to setup the environment).
