[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1572) sometimes getting ClassFieldExtractor error

[ http://jira.jboss.com/jira/browse/JBRULES-1572?page=comments#action_12411683 ] Mark Proctor commented on JBRULES-1572: --------------------------------------- I've created the following unit test, based of your example: public void testMultiThreadOnSingleSession() throws Exception { String str = "package org.drools.test\n" + "import org.drools.Person\n" + "rule \"Auto Retract\"" + "when\n" + " person:Person()\n" + "then\n" + " retract(person);\n" + "end\n"; RuleBase ruleBase = RuleBaseFactory.newRuleBase(); PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(new StringReader( str ) ); Package pkg = builder.getPackage(); ruleBase.addPackage(pkg); final WorkingMemory workingMemory = ruleBase.newStatefulSession(); workingMemory.addEventListener(new DebugAgendaEventListener()); Runnable runnable = new Runnable() { public void run() { while (true) { workingMemory.insert(new Person( "bobba fet", 35)); workingMemory.fireAllRules(); } } }; Thread thread1 = new Thread(runnable, "thread1"); Thread thread2 = new Thread(runnable, "thread2"); thread1.start(); thread2.start(); Thread.sleep( 15000 ); } However I'm not able to reproduce the problem, on my single cpu laptop. Is this a problem that only becomes visible on multiple cpus? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
