Hi Erik, Short answer is, no, we haven't changed the DN versions for this release - that's gonna happen in Isis 2.0.0-M1 but not before. And I can't, off the top of my head, think of anything in Isis 1.16.x that's changed in this area.
Some questions/suggestions: - is this failing for every entity instance/row? StreamCorrupted suggests a probably with an individual field - does the 1.15.x version of your app work with this specific entity instance/row - is this entity instance particularly large? is there a limit being hit? - if you write a simple DN-only app (no Isis) to retrieve the row, does it work or fail? - if 1.15.x works but 1.16.x, can you isolate from the stack trace where 1.16.x is throwing an exception whereas 1.15.x continues happily? Sorry don't have an immediate solution for you...
