There are two issues:
1. There is something wrong with some class loader involved.
Thread.currentThread().getContextClassLoader().loadClass("javax.faces.context.FacesContext")
must never return null. If it can't load a class, it should throw
ClassNotFoundException or some exception. I see following code in
WebappClassLoader.loadClass():
/ // Don't load classes if class loader is stopped
if (!started) {
logger.log(Level.SEVERE, "webappClassLoader.stopped", name);
return null;
}
/
2. WebappClassLoader returning null is not the actual cause of
regression. It appears that it has not been started yet. So, some change
in deployment or web container might have caused this.
This also explains the java.lang.NullPointerException at
javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:129).
This is the same problem that Amy has encountered in embedded use case.
