when deserializing objects with references to themselves, ObjectInputStream pointlessly marks the object as a dependency of itself, which increases memory required to deserialize certain memory graphs.
bug: https://bugs.openjdk.java.net/browse/JDK-6823565 webrev: http://cr.openjdk.java.net/~redestad/6823565/webrev.01/ Looks fine. A comment in markDependency should probably be updated to explain that self-referenced objects are skipped.
Thanks for reviewing, Aleksey!
How about "Additionally, no action is taken if the dependent and target are the same."?
