[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2057) Collection returned by StatefulKnowledgeSession.getObjects() doesn't conform to standard collection behaviour

Collection returned by StatefulKnowledgeSession.getObjects() doesn't conform to standard collection behaviour ------------------------------------------------------------------------------------------------------------- Key: JBRULES-2057 URL: https://jira.jboss.org/jira/browse/JBRULES-2057 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.0.0.CR1 Reporter: Damon Horrell Assignee: Mark Proctor Attachments: drools-bug-tests.zip StatefulKnowledgeSession.getObjects() returns a collection containing the objects in working memory. The Javadoc for Collection.contains says: "Returns true if this collection contains the specified element. More formally, returns true if and only if this collection contains at least one element e such that (o==null ? e==null : o.equals(e)). " This is not the case though for StatefulKnowledgeSessionImpl.ObjectStoreWrapper. The implementation of contains returns true only if it is the exact same object instance, but false if it is a different instance but which equals the instance in the working memory. A workaround is to create a new collection and put the items returned into that.
