[jboss-jira] [Red Hat JIRA] (WFLY-14285) Serialization Errors with EJB over HTTP

Serialization Errors with EJB over HTTP --------------------------------------- Key: WFLY-14285 URL: https://issues.redhat.com/browse/WFLY-14285 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 21.0.0.Final, 21.0.1.Final, 21.0.2.Final Reporter: Adriano Teixeira de Souza Assignee: Cheng Fang Priority: Major Attachments: serialization-wf-21-0-2.txt We are testing our application for upgrade to las version of Wildfly (21.0.2) and on the ejb client over http in a standalone client application we are facing many serialization errors that doesn't have on previous versions (20.0.1 and before) It occurs after 6 times executing a function that call remote ejb. The errors is some times like this: {code:java} Caused by: java.lang.ClassCastException: Cannot cast java.lang.Class to java.util.Date at java.lang.Class.cast(Class.java:3605) at org.jboss.marshalling.reflect.SerializableField.setObject(SerializableField.java:342) at org.jboss.marshalling.river.RiverUnmarshaller.readFields(RiverUnmarshaller.java:1864) at org.jboss.marshalling.river.RiverUnmarshaller.doInitSerializable(RiverUnmarshaller.java:1778) at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1406) ...
