Re: [eclipselink-users] the SQL-update statement happens while Eclipselink is looking for a record 
Could you include you class including its mapping.

My guess is the special Oracle types you are using are some how confusing
EclipseLink's change tracking, such that it thinks they have changed. 
Actually I'm surprised you don't get an error that your not allowed to
update a primary key.
