Jon Kranes created DROOLS-1233: ---------------------------------- Summary: Memory references to removed facts are retained for certain rules Key: DROOLS-1233 URL: https://issues.jboss.org/browse/DROOLS-1233 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.4.0.Final Reporter: Jon Kranes Assignee: Mario Fusco Attachments: drools-memory-test.zip, gc-root.tiff, heap-dump.tiff 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of a specific pattern, Drools maintains references in a stateful session to fact objects even after the facts have been withdrawn from working memory.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. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
