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

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%. -- John O'Hara johara(a)redhat.com JBoss, by Red Hat Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SI4 1TE, United Kingdom.
