[weld-issues] [JBoss JIRA] (WELD-600) Unable to deserialize Javassist proxy due to wrong classloader being used

Unable to deserialize Javassist proxy due to wrong classloader being used ------------------------------------------------------------------------- Key: WELD-600 URL: https://issues.jboss.org/browse/WELD-600 Project: Weld Issue Type: Bug Components: Servlet Container Support Environment: Apache Tomcat 6.0.20 Reporter: Fabio Wang Fix For: TBC Attachments: Action.java, action.xhtml, Bean.java, jersey-gf-bundle.jar, template.xhtml Trying to mark a conversation as long-running causes an exception (java.lang.NoClassDefFoundError: javassist/util/proxy/ProxyObject) when the ServletConversationManager tries to get a proxy for the httpSession. The ProxyFactory.classLoaderProvider ends up resolving the classloader to an instance of org.apache.catalina.loader.StandardClassLoader (which doesn't know the javassist lib, since it's only in the app classloader).
