Steve Brewin commented on JAMES-1440:
-------------------------------------
In JPA, lazy fetching is only useful when the data to be fetched is
infrequently referenced and is expensive to fetch. Generally it is cheaper to
fetch all data eagerly as this can be achieved in a single visit to the
database.
All of the fields annotated with fetch=FetchType.LAZY in
org.apache.james.mailbox.jpa.mail.model.openjpa.AbstractJPAMessage are
frequently referenced. These should be changed to fetch=FetchType.EAGER to
avoid multiple visits to the database.
I'll fix it!
