Java does *not* have problems with circular references.



Java does some bookkeeping of what objects hold references


to what other objects. Once the GC happens, it will detect


all objects that have a live (not just any) reference on it,


and any clusters of circular referenced objects that are not


also referenced from outside are swept away.



This kind of GC does require a deep knowledge of all


involved types, and may be somewhat expensive (more than


ref-count based GC), but it definitely doesn't leak for


circular refs.
