Resolution

This UnsupportedOperationException is thrown when any exception hppens inside Content from github.com is not included.com.sun.faces.application.WebappLifecycleListener#requestDestroyed() of JSF implementation (mojarra).

A possible cause might be an exception (IllegalStateException) which is thrown at HttpSession.setAttibute() operation in mojarra's lister because of session invalidation (or expiration). However, as JSF implementation (mojarra) swallows an original exception, it's not possible to identify the root cause from the current log. We raised This content is not included.JBEAP-28797 to improve logging in mojarra.

If the issue is reproducible, you can log the original exception and output log when session is initialized and invalidated by using byteman debug rule like the following. Also refer to this article for details about using byteman.

RULE Debug_log_exception_at_new_ExceptionQueuedEventContext_from_requestDestroyed
CLASS javax.faces.event.ExceptionQueuedEventContext
METHOD <init>(javax.faces.context.FacesContext, java.lang.Throwable)
AT ENTRY
IF callerEquals("com.sun.faces.application.WebappLifecycleListener.requestDestroyed", true, true) && $2 != null
DO $2.printStackTrace();
ENDRULE

RULE Debug_session_init
INTERFACE javax.servlet.http.HttpSession
METHOD <init>
AT EXIT
IF TRUE
DO traceStack("---------------------------> HttpSession is initiallized. session id = " + $0.getId() + "\n");
ENDRULE

RULE Debug_session_invalidate
INTERFACE javax.servlet.http.HttpSession
METHOD invalidate
AT EXIT
IF TRUE
DO traceStack("---------------------------> HttpSession is invalidated. session id = " + $0.getId() + "\n");
ENDRULE
