Volodymyr Siedlecki commented on MYFACES-4639:
----------------------------------------------
Question: Should I duplicate the whole ClassUtils class to avoid further errors
like this or just copy over the newInstance methods into the impl ...?
> Implementation ClassUtils needs "newInstance" methods added to support OSGI
> runtimes

> Key: MYFACES-4639
> URL: https://issues.apache.org/jira/browse/MYFACES-4639
> Project: MyFaces Core
> Issue Type: Bug
> Reporter: Volodymyr Siedlecki
> Priority: Major
>
> This is basically the same issue as
> https://issues.apache.org/jira/browse/MYFACES-4449
> This variant was originally reported here:
> [https://github.com/OpenLiberty/open-liberty/issues/26760]
> However, the CNFE occurs with the newInstance methods since the classes are
> looked up via the API classloader and therefore not found (since the classes
> exist in the Impl and OSGI creates seperate between bundles. See the
> discussion in 4449 for more information)
> Example of error:
> [ERROR ] Class org.apache.myfaces.push.WebsocketInitRenderer not found
> org.apache.myfaces.push.WebsocketInitRenderer cannot be found by
> io.openliberty.jakarta.faces.4.0_1.0.84.202311061333
> This error is related to whether the renderkit is an instance of
> LazyRenderKit. If it's not, then the standard form look up used (via
> newInstance).
> LazyRenderKit code was added via MYFACES-3815 :
> [https://github.com/apache/myfaces/commit/93a2ddf060d04cea658f58f9223c22b5badeea90]
>
> I'm not entirely sure how this happens in the users case above, but we should
> move these methods again to avoid these errors. I'll have a PR up soon.
