Aleksei,
We had such a problem in our work project (not JAXB -
related). See [1] for limitation of Java serialization. I
hadn't tried the example in JDK 1.4+, but we had an
extremely deep structure (the problem ahs nothing to do
with circularity).
I've poked a little bit around HotSpot code for
serialization, and each hierarchy level is translated to 4
or 5 recursive calls - the serialization is recursive and
not iterative (DFS in the worst sense).
