Alessandro Lazarotti created DROOLS-1361: -------------------------------------------- Summary: Infinite loop when updating a fact inside a shared subnetwork Key: DROOLS-1361 URL: https://issues.jboss.org/browse/DROOLS-1361 Project: Drools Issue Type: Bug Components: core engine Reporter: Alessandro Lazarotti Assignee: Mario Fusco Priority: Critical Updating a fact evaluated inside a shared subnetwork may cause an infinite loop as demonstrated by the following unit test: {code} @Test(timeout = 10000L) public void testUpdateOnSharedSubnetwork() { String drl = "import " + AtomicInteger.class.getCanonicalName() + ";\n" + "global java.util.List list;\n" + "rule R1y when\n" + " AtomicInteger() \n" + " Number() from accumulate ( AtomicInteger( ) and $s : String( ) ; count($s) )" + " eval(false)\n" + "then\n" + "end\n" + "\n" + "rule R2 when\n" + " $i : AtomicInteger( get() < 3 )\n" + "then\n" + " $i.incrementAndGet();" + " insert(\"test\" + $i.get());" + " update($i);" + "end\n" + "\n" + "rule R1x when\n" + " AtomicInteger() \n" + " $c : Number() from accumulate ( AtomicInteger( ) and $s : String( ) ; count($s) )\n" + " eval(true)\n" + "then\n" + " list.add($c);" + "end\n"; KieSession kieSession = new KieHelper().addContent( drl, ResourceType.DRL ) .build().newKieSession(); List<Number> list = new ArrayList<Number>(); kieSession.setGlobal( "list", list ); kieSession.insert( new AtomicInteger( 0 ) ); kieSession.insert( "test" ); kieSession.fireAllRules(); assertEquals(1, list.size()); assertEquals(4, list.get(0).intValue()); } {code} -- This message was sent by Atlassian JIRA (v7.2.3#72005)
