[ https://issues.jboss.org/browse/WFLY-6665?page=com.atlassian.jira.plugin.... ] Kamil Podlešák updated WFLY-6665: --------------------------------- Description: When unmarshalling of session throws _unexpected_ exception, it is not handled correctly and is propagated to undertow worker, thus causing generic http 500 error to be shown to user. Problem is that each request tries to unmarshall session again and fails... making this session completely broken with no recovery until session cookie expires or is removed (ie browser closed). Some exceptions are _expected_ and handled correctly by removing session and continuing (usually, new session is created). They are catched in MarshalledValueMarshaller.read, wrapped by InvalidSerializedFormException and then handled in CoarseSessionAttributesFactory.findValue. Expected exceptions are these: * java.lang.ClassNotFoundException * java.io.InvalidClassException * java.io.InvalidObjectException This list is sufficient in *most* of the time, but sometimes even jboss-marshalling-river throws some RuntimeException (not to mention IOException). Note: application must be marked as "distributable" in web.xml or equivalent. Sample stacktrace (there are several possible variants): {noformat} 14:26:14,366 ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (default task-1) ISPN000136: Error executing command
