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."? http://cr.openjdk.java.net/~redestad/6823565/webrev.02/

Good.

Thanks, -Aleksey
