> Given a simple rule of a specific pattern, Drools maintains references in a stateful session to fact objects even after the facts have been withdrawn from working memory.
> For example, given the following rule:
> {code}
> rule "TestRule"
> 	when
> 		$tc : TestClass()
> 		not TestClass2(name == $tc.name)
> 	then
> 		insert(new TestClass2($tc.getName()));
> 	end
> {code}
> Drools will maintain an internal reference to instances of TestClass even after they have been explicitly deleted from the session.
