Steps to Reproduce:

Hide

Create session attribute containing an unmodifiable collection of immutable objects.
e.g.
HttpSession.setAttribute("foo", Collection.singleton("bar"));

On subsequent request, lookup attribute created above.
e.g.
HttpSession.getAttribute("foo");

Session replicates at the end of the request, even though the session attribute is immutable.

Unmodifiable collections include:
Collections.empty*();
Collections.singleton*();
Collections.unmodifiable*();

where the collection contents are also immutable.
