PojoCache InternalDelegate can return incorrect AOPInstance object ------------------------------------------------------------------ Key: JBCACHE-268 URL: http://jira.jboss.com/jira/browse/JBCACHE-268 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: PojoCache Affects Versions: PojoCache Reporter: twundke Assigned To: Ben Wang The getAopInstance(Fqn) method of InternalDelegate currently uses a cache.peek() call to find the AOPInstance object for an FQN. However, I've come across a situation where multiple calls to this method for the same FQN will return different AOPInstance objects. To be honest, I'm not sure of the exact situation in which this occurs as I haven't delved deep enough. However, the basic idea is that I have an object graph in the cache, all hanging off one particular root-level object. I then do a fairly major addition/update to a number of children, but don't specifically update the root-level object. After this update I find that InternalDelegate returns a new instance of the AOPInstance class for the root object's FQN, which has now lost its POJO reference etc. This in turn forces a re-creation of the root-level object, which loses a number of transient references that I have set. Note that my object graph has a number of circular references back to this root-level object, so I suspect that the AOP machinery is for some reason updating this object during the update of the children, thereby losing the original AOPInstance reference. I've put in a quick fix locally that caches references to AOPInstance objects in a HashMap, which follows the idea suggested in the comment for the method. This solves the issue.
