[jboss-jira] [JBoss JIRA] Assigned: (JBAS-3952) Problem with SerializableProxy when de-serializing in a remote client

Problem with SerializableProxy when de-serializing in a remote client --------------------------------------------------------------------- Key: JBAS-3952 URL: https://jira.jboss.org/jira/browse/JBAS-3952 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB3, Hibernate service Affects Versions: JBossAS-4.0.5.GA Environment: Windows Vista and Windows XP, Java 1.5.0 Update 10 and Java 1.6.0 Reporter: Frank Ulbricht Assignee: Carlo de Wolf Attachments: testcase.zip After calling a SessionBean method that returns an entity with a lazy relation there is an problem with de-serialization on the client side. The lazy field cannot not be assigned because of a ClassCastException. In other projects the same happens after a method returns the result of a query where lazy fields are involved. The problem occurs only with lazy fields. The is a simple test case attached with the problem code line marked. Here is the complete stacktrace: java.lang.reflect.UndeclaredThrowableException at $Proxy6.updateAddress(Unknown Source) at com.qualitype.testcase.client.RemoteClientTestCase.test(RemoteClientTestCase.java:48) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.internal.runners.TestMethodRunner.executeMethodBody(TestMethodRunner.java:99) at org.junit.internal.runners.TestMethodRunner.runUnprotected(TestMethodRunner.java:81) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34) at org.junit.internal.runners.TestMethodRunner.runMethod(TestMethodRunner.java:75) at org.junit.internal.runners.TestMethodRunner.run(TestMethodRunner.java:45) at org.junit.internal.runners.TestClassMethodsRunner.invokeTestMethod(TestClassMethodsRunner.java:71) at org.junit.internal.runners.TestClassMethodsRunner.run(TestClassMethodsRunner.java:35) at org.junit.internal.runners.TestClassRunner$1.runUnprotected(TestClassRunner.java:42) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34) at org.junit.internal.runners.TestClassRunner.run(TestClassRunner.java:52) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:38) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Caused by: java.rmi.MarshalException: Failed to communicate.
