[hibernate-dev] HHH-9857 - Reuse of EntityEntry for bytecode enhanced read-only reference cached entities

[John O'Hara]

For our use case, bytecode enhanced reference cached immutable entities, 
our top object for memory allocation is EntityEntry.

We see an EntityEntry object created every time an immutable entity is 
added to a persistence context.

In our use case, where we know the entity is immutable and we already 
have an EntityEntry cached, can we re-use the EntityEntry between 
sessions? This would reduce the allocation rate of EntityEntry in our 
use case by ~50%.
