[jboss-user] [JBossCache] - Cross-reference problem

Hi guys! We've met a problem with JBoss cache and we don't know if it's a bug or usage problem. We have an annotated User class wich has an ArrayList buddies property. We put two instances of User class to the cache and each instance has a reference to another one from the buddies list. The code is like this: | User user1 = new User(); | User user2 = new User(); | cache.putObject(user1.getFqn(), user1); | cache.putObject(user2.getFqn(), user2); | //skipped | user1.getBuddies().add(user2); | //skipped | user2.getBuddies().add(user1); | On some event we are removing user1 from the cache: | user2.getBuddies().remove(user1); | cache.removeObject(user1.getFqn()); | And then we are putting it again: | cache.putObject(user1.getFqn(), user1); | user2.getBuddies().add(user1); | This last line of code throws IllegalStateException with the following message: AopInstance.incrementRefCount: source fgn /users/user1 is already present. After a small debugging we added following befor removing user1 from cache: user1.getBuddies().clean(); And all the problems are gone. So, should we really remove all the references to the cached objects from user1 before removing it from the cache or it's a problem of illegal usage?
