[jboss-jira] [JBoss JIRA] (JBRULES-3217) Memory leak in stateless session when using CommandFactory.newInsertElements()

Memory leak in stateless session when using CommandFactory.newInsertElements() ------------------------------------------------------------------------------ Key: JBRULES-3217 URL: https://issues.jboss.org/browse/JBRULES-3217 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Mario Fusco Assignee: Mario Fusco Priority: Critical Description of problem: There is a memory leak when calling an execute method on StatelessKnowledgeSession with list of Commands(facts). See the reproducer. According to heap dump, the org.drools.command.runtime.rule.InsertElementsCommand is holding references to facts even after the execute() method is finished. This is a regression from 5.1.0 GA. Version-Release number of selected component (if applicable): BRMS 5.2.0 ER3 How reproducible: Always Steps to Reproduce: 1. Run the attached reproducer with ER3 binaries on classpath. 2. Look at stdout to see the raising heap used memory. Actual results: Heap used memory is raising. Expected results: Heap used memory is not raising. All unused object are collected. Additional info: When jBPM jars are not included in classpath, leak is away and memory usage in not raising. Memory leak does not occur when StatefulKnowledgeSession is used. Reported in bugzilla as: https://bugzilla.redhat.com/show_bug.cgi?id=734367
