Hi,

i'm new to this, but i have something for the "HHH000072: Duplicate joins for class:".

I've tested the new version. In the class "org.hibernate.boot.internal.InFlightMetadataCollectorImpl" was this message thrown,
after using following code:
MetadataSources metadataSources = new MetadataSources(standardServiceRegistry).addAnnotatedClass(....class).addAnnotatedClass(....class).addAnnotatedClass(....class);
MetadataBuilder metadataBuilder = metadataSources.getMetadataBuilder();
Metadata metadata = metadataBuilder.build();

After "metadataBuilder.build()" my 3 classes from addAnnotatedClass where duplicated. I saw this in the method "imports" from "MetadataImpl".

Hope it could help for resolving.

PS: If i had made a mistake for posting this here, please moved or delete it.
