Hi Michael,

You can try dataContext.unregisterObjects() or
dataContext.invalidateObjects() if you need to keep other things in
your DC around. If not, throwing away the DC for a new one is a good
approach.
DataContext.invalidateObjects() seems to have the desired effect. I have
to invalidate all objects, including the RecipientSet object which holds
the references to the Recipient objects. I'll do some testing if
everything still works as expected :)
Thanks a lot for your reply!
Best regards,

Hi everyone,
I'm facing the following situation:
RecipientSet has many Recipients
A large number of Recipient objects are imported in a single transaction.
The changes are committed e.g. every 100 recipients. Nevertheless the
Recipient objects are kept in the heap, and eventually an OutOfMemoryError
occurs.
I have the feeling that the Recipient objects cannot be garbage-collected
because of the relationship references from the RecipientSet. I didn't find
any other references to the Recipient objects.
Is it possible to tell Cayenne not to keep the references, or is there any
other way to handle this issue? Do I have to create a new data context after
the changes are committed, starting with a fresh RecipientSet?
Thanks a lot in advance for any hints!
Best regards,
Andreas
