[jboss-jira] [JBoss JIRA] Closed: (JBRULES-977) Foo(this != $i) fails when using ShadowProxy

Foo(this != $i) fails when using ShadowProxy -------------------------------------------- Key: JBRULES-977 URL: http://jira.jboss.com/jira/browse/JBRULES-977 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.0.MR4 Reporter: Brian Stiles Assigned To: Edson Tirelli Fix For: 4.0.0.MR4 The self reference field "this" doesn't behave as expected when shadow proxies are used. when $i : Foo() Foo(this != $i) the above always fires. The following code exhibits the problem. -------- /* * Created on Apr 26, 2007 */ package sample; import java.io.StringReader; import org.drools.RuleBase; import org.drools.RuleBaseConfiguration; import org.drools.RuleBaseFactory; import org.drools.StatefulSession; import org.drools.compiler.PackageBuilder; import org.drools.compiler.PackageBuilderConfiguration; public class ThisProblem { public static class Foo { private final int _number; public Foo(int number) { _number = number; } public int getNumber() { return _number; } public int hashCode() { return _number; } public boolean equals(Object obj) { if (obj == this) { return true; } if (obj instanceof Foo) { final Foo other = (Foo) obj; return _number == other._number; } return false; } public String toString() { return String.valueOf(_number); } } public static void main(String[] args) throws Exception { fail(); System.out.println("********************************************"); succeed(); } private static void fail() throws Exception { test(true); } private static void succeed() throws Exception { test(false); } private static void test(boolean useShadowProxy) throws Exception { final PackageBuilderConfiguration packageBuilderConfiguration = new PackageBuilderConfiguration(); final PackageBuilder packageBuilder = new PackageBuilder(packageBuilderConfiguration); packageBuilder.addPackageFromDrl(new StringReader("\n" + "package sample\n" + "\n" + "import sample.ThisProblem.Foo;" + "\n" + "rule MyRule\n" + " dialect \"java\"\n" + "\n" + " when\n" + " $i : Foo()\n" + " $k : Foo(this != $i)\n" + " then \n" + " System.out.println(\"-------------\");\n" + " System.out.println($i + \": \" + System.identityHashCode($i));\n" + " System.out.println($k + \": \" + System.identityHashCode($k));\n" + "end \n")); final RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration(); ruleBaseConfiguration.setShadowProxy(useShadowProxy); final RuleBase ruleBase = RuleBaseFactory.newRuleBase(ruleBaseConfiguration); ruleBase.addPackage(packageBuilder.getPackage()); final StatefulSession session = ruleBase.newStatefulSession(); session.insert(new Foo(1)); session.fireAllRules(); } }
