> 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.
