Problem summary
**************************************************************** * USERS AFFECTED: WebSphere eXtreme Scale clients that use * * eXtreme Scale HTTP session management and * * splicer property, listenerMode=false * **************************************************************** * PROBLEM DESCRIPTION: The following error occurs: * * CWWSM0004E: Caught a data grid * * exception * * java.util.NoSuchElementException as * * seen in the logs * **************************************************************** * RECOMMENDATION: * **************************************************************** WebSphere eXtreme Scale assumes that a JSESSIONID cookie is either not present (null) or present with a valid session value. However, if an application has set the JSESSIONID to an empty string (or invalid value) (for example, during an application logout), then eXtreme Scale does not handle the unexpected value and produces an exception in the logs.
Problem conclusion
WebSphere eXtreme Scale now handles empty string (and invalid values) for JSESSIONID and no longer produces an exception.
Temporary fix
