[jboss-jira] [JBoss JIRA] (WFLY-3234) Wrong JSF class loaded in third dependencies

[Farah Juma (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12960534#comment-12960534 ] 

Farah Juma commented on WFLY-3234:
----------------------------------

Note that this is a known Mojarra issue:

https://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-1257

As mentioned in the above issue, the FaceletContext.FACELET_CONTEXT_KEY constant will hopefully no longer be inlined by the compiler in JSF 2.3.

> I have a web project, war, who use a third maven dependency which load java ee 6 dependency with provided scope:
> <dependency>
>             <groupId>javax</groupId>
>             <artifactId>javaee-web-api</artifactId>
>             <version>6.0</version>
>             <scope>provided</scope>
> </dependency>
> In runtime the third dependency tries to load a FaceletContext and to ensure compatibility it uses the constant from javax.faces.view.facelets.FaceletContext.FACELET_CONTEXT_KEY which fails because the constant returns the old constant from java ee 6 version, com.sun.faces.facelets.FACELET_CONTEXT instead of javax.faces.FACELET_CONTEXT from java ee 7.
> If I try the same code from a class in war project it loads the right constant and works.
> E.g.
> public FaceletContext getFaceletContext() {
>         final FacesContext currentInstance = FacesContext.getCurrentInstance();
>         return (FaceletContext) currentInstance.getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);
> //from third dependency "com.sun.faces.facelets.FACELET_CONTEXT"
> //from classes in war "javax.faces.FACELET_CONTEXT" 
> }
> I've created it with critical priority because it broke compatibility with some jsf frameworks.
> Attached the project where I could simulate
