After almost a year without any problem suddenly my Glassfish web application is not working any more. In the browser the requested pages are truncated and bad formatted. The log is full of the following exceptions:
[2016-01-04T17:45:21.263+0100] [glassfish 4.0] [WARNING] [] [javax.enterprise.web.core] [tid: _ThreadID=22 _ThreadName=http-listener-1(5)] [timeMillis: 1451925921263] [levelValue: 900] [[

Servlet.service() for servlet Faces Servlet threw exception
java.lang.IllegalStateException: A request must be associated with the context in order to load the known conversations
and others related perhaps to a poorly configured error page. It seems that glassfish responds with a 500 internal error to requests like this: www.mysite/faces/javax.faces.resource/primefaces.css?ln=primefaces&v=4.0
In internet I found the following related posts:
From the above documentation it is clear that Glassfish 4 has some bugs and it is not wise to use it in production. I wonder why everything seemed to work well for more than a year and suddenly it broke. The third link suggests it may be due to an external attack and it provides a patch I'm going to test. Is it correct or am I misunderstanding something ?
