If there's a container EReference and if that's not transient, it will
serialize that. So you could make that transient, but you've not
mentioned having such a reference.

By making it transient. Otherwise, it sounds like a
DanglingHREFException so you can set an exception breakpoint (the little
J! icon in the Breakpoints view) and see which reference is causing the
problem. Or you can use
just ignore them.
