Bridge methods are proxied instead of desired methods ----------------------------------------------------- Key: JASSIST-189 URL: https://issues.jboss.org/browse/JASSIST-189 Project: Javassist Issue Type: Bug Affects Versions: 3.17.1-GA Environment: OS X, Java 1.7.0_09 Reporter: Donnchadh Ó Donnabháin Assignee: Shigeru Chiba Fix For: 3.18.0-GA The following test intermittently fails: {code} package org.javassist.test.covariantproxy; import java.lang.reflect.Method; import javassist.util.proxy.MethodHandler; import javassist.util.proxy.ProxyFactory; import javassist.util.proxy.ProxyObject; import junit.framework.TestCase; public class CovariantProxyTest extends TestCase { public interface TestProxy { } public static class TestMethodHandler implements MethodHandler { boolean invoked = false; public Object invoke(Object self, Method thisMethod, Method proceed, Object[] args) throws Throwable { invoked = true; return proceed.invoke(self, args); } public boolean wasInvoked() { return invoked; } public void reset() { invoked = false; } } public static class Issue { private Integer id; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } } public static class PublishedIssue extends Issue { } public static abstract class Article { private Integer id; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public abstract Issue getIssue(); } public static class PublishedArticle extends Article { private PublishedIssue issue; @Override public PublishedIssue getIssue() { return issue; } public void setIssue(PublishedIssue issue) { this.issue = issue; } } public void testThatCallingAMethodWithCovariantReturnTypeCallsProxy() throws Exception { Class persistentClass = PublishedArticle.class; ProxyFactory factory = new ProxyFactory(); factory.setUseCache(false); factory.setSuperclass(persistentClass); factory.setInterfaces(new Class[] {TestProxy.class}); Class cl = factory.createClass(); TestProxy proxy = ( TestProxy ) cl.newInstance(); TestMethodHandler methodHandler = new TestMethodHandler(); ( ( ProxyObject ) proxy ).setHandler( methodHandler ); ((Article)proxy).getIssue(); assertTrue(methodHandler.wasInvoked()); methodHandler.reset(); PublishedArticle article = (PublishedArticle) proxy; article.getIssue(); assertTrue(methodHandler.wasInvoked()); } } {code} Were there tests added for JASSIST-24 ? I don't see any associated source. This bug causes a problem in hibernate, described in https://hibernate.onjira.com/browse/HHH-7884 . This may be related to JASSIST-162 but the circumstances are slightly different. The problem occurs intermittently so it appears to depend on the order in which the methods are processed.
