Demo is attached.
Run the code with & without byte code enhancement.
* *Problem with non-enhanced mode is that all optional one to ones are fetched as soon as the root entity is fetched**
* Post* has two OneToOne relationships.
1. *AdditionalDetails*
2. *OptionalOneToOneDetails*
Without enhancement, the initialization of *AdditionalDetails* relationship works fine.
{code:java}
Hibernate.initialize(post.getAdditionalDetails());
{code}
After enhancing the bytecode, I get this exception
{code:java}
INFO: HHH000327: Error performing load command : org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.acme.OptionalOneToOneDetails#1]
