Fluent querying can lead to invalid entity graph if multiple children nodes of a same child node are queried #318

What steps will reproduce the problem ?

Steps to reproduce the behavior:

1. Build an entity graph with at least 2 children nodes from a same attribute.
2. Try calling a EntityGraphJpaSpecificationExecutor#findBy(Specification, EntityGraph, Function)
   with it.

What is the expected output ?

It should return the queried result.

What happens instead ?

You end up with a org.springframework.data.core.PropertyReferenceException because it cannot find properties you asked for.

Environment
