[jira] [Comment Edited] (MYFACES-4469) "java.lang.IllegalArgumentException: object is not an instance of declaring class" occurs in FacesConfigurator.purgeConfiguration
[ https://issues.apache.org/jira/browse/MYFACES-4469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17701824#comment-17701824 ]

Reopening – I have a successful fix for the user who experienced this issue.
They create war in one time zone (difference of 1 hour), but deploy in another. Once an hour passes, the exception occurs.
Somehow this triggers the code to call the purgeConfiguration code here: [https://github.com/apache/myfaces/blob/4a996076a298b3767dab5e16fd312d5221e6b14a/impl/src/main/java/org/apache/myfaces/config/FacesConfigurator.java#L383-L394]
Fix is fairly simply as all we need to do is unwrap the objects to ensure we invoke the methods on the right classes.
I'll update the existing PR in a bit.

> Affects Versions: 4.0.0-RC1, 2.3.10, 2.3-next-M7, 3.0.2

> If an application uses a custom factory via META-INF/services (such as javax.faces.application.ApplicationFactory), then a purge failure can occur when in *development mode* when an *update occurs to the faces-config.xml.* Additionally, the server must not restart the application (which can occur).

> getPurgeMethod unwraps the factory to get the method, but it then calls the private method on the wrong class ( which doesn't have that purge method)
