OOME on Marshalling (JPA), caused by infinite cycle on OutputMarshaller.writeLeftTuple -------------------------------------------------------------------------------------- Key: JBRULES-2724 URL: https://jira.jboss.org/browse/JBRULES-2724 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.1.1.FINAL Environment: OpenSuse Linux, java version "1.6.0_21" Reporter: Dan Danciu Assignee: Kris Verlaenen Fix For: 5.2.0.M1 Attachments: OutputMarshaller-DanDanciu.patch When trying to marshal my stateful session (spring configured) using JPA, the tests failed with OutOfMemoryError. After tracing the OOEM, I found the fault in a infinite loop in org.drools.marshalling.impl.OutputMarshaller, method writeLeftTuple, for the cases: NodeTypeEnums.NotNode, NodeTypeEnums.ForallNotNode and NodeTypeEnums.ExistsNode. The problem was that childLeftTuple was not taken from childLeftTuple but from leftTuple, causing the infinite loop. Sorry, I cannot give you more info on how to reproduce the problem, for us it appears only in an certain integration test, but I did create a patch, and our code works with it.
