Mysterious "Attempt to persist a reference to a non managed instance" error
I've been working with ObjectDB for the past several months, and it's behaved pretty much as expected.

The thing to note is that the Index structure is recursive through maps; but that's never caused any problem for me in the past. ... package failing ; import java. io . Serializable ; import javax. persistence . Entity ; ... Entity public class Ostrich implements Serializable { @ Id long id ; public ...
