Websphere 8.5 - JSF webapp context init error: cleanupInitMaps

Question

I have got a JSF 2.1 web application developed with mojarra 2.1.17 distibution which run with any problems on JBoss 6.1 container: now i have to change application server and I have to use websphere AS 8.5 which were born with MyFaces JSF 2 distibution. I'm trying to deploy and start my webapp ignoring MyFaces and using Mojarra, configuring my EAR as IBM official guide shows, configuring shared lib with mojarra dist included, link it to a new classloader created exclusively for my server1 instance of WAS 8.5. It doesn't work at all and when I deploy my webapp i get this stacktrace when WAS try to start the application:

I debugged cleanupInitMaps() method of mojarra dist too and i saw that it tries to get two Map of kind of variable from FacesContext called threadInitContext and initContextServletContext but gets null:

Field threadMap = FacesContext.class.getDeclaredField("threadInitContext");
and 
Field initContextMap = FacesContext.class.getDeclaredField("initContextServletContext");

How is this caused and how can I solve it?

Answer 1

Ok, i solved it !! first of all i set classloader of my server instance to PARENT_LAST + restart. Then i followed these steps: 1) put Mojarra lib into simple shared library; 2) deploy ear with jsf web module inside and before start application from console, i linked shared lib to it and to all modules inside ear; 3) i set application classloader to PARENT_LAST; 4) start app and it works !!

That's all !!
