> from the scenario in [JBPAPP-11027|https://issues.jboss.org/browse/JBPAPP-11027] , and java code in java/javax/el/BeanELResolver.java :
> {code:title=BeanELResolver.java|borderStyle=solid}
>         Iterator<Class<?>> iter = cache.keySet().iterator();
>         while (iter.hasNext()) {
>             Class<?> key = iter.next();
>             BeanProperties bp = cache.get(key);
>             if(bp.getType().getClassLoader().equals(classloader)){
>                 iter.remove();
>             }
>         }
> {code}
> Here, when key is "class java.lang.Class" and bp's type is "class java.lang.Class", method getClassLoader() returns null to represent the bootstrap class loader, then NPE as described is threw during stopping service jboss.web
