[jira] [Commented] (GERONIMO-6330) NPE in CompositeELResolver

["Jarek Gawor (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GERONIMO-6330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13257049#comment-13257049 ] 

Jarek Gawor commented on GERONIMO-6330:
---------------------------------------

The problem is that the CompositeELResolver was iterating over the resolvers array directly instead of relying on the size field.
Fix committed in revision 1327712.

> When you create an application which contains a JSF mapping in your web.xml file, JSP (JavaServer *Pages*) files which contain an EL function, throw a NPE. Here is the web.xml changes I added to a small JSP application:
>   <servlet>
>     <servlet-name>Faces Servlet</servlet-name>
>     <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
>     <load-on-startup>1</load-on-startup>
>   </servlet>
>   <servlet-mapping>
>     <servlet-name>Faces Servlet</servlet-name>
>     <url-pattern>/faces/*</url-pattern>
>     <url-pattern>*.jsf</url-pattern>
>   </servlet-mapping>
> After doing this and deploying the application, the following page throws an NPE:
> hello.jsp:
>   Test: '${pageContext.getRequest()}'
> Exception:
> java.lang.NullPointerException
