[jboss-jira] [JBoss JIRA] (JBWEB-279) Overlays do not work as expected

[Remy Maucherat (JIRA)]

    [ https://issues.jboss.org/browse/JBWEB-279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12800919#comment-12800919 ] 

Remy Maucherat commented on JBWEB-279:
--------------------------------------

That functionality is used to implement the spec behavior. Some configurability was added since it appeared to be easy and cheap to do, but as a result it inherits the same behavior. A configuration option can be added to switch that (disabled by default) but the switch can break spec compliant webapps.

> It is expected that the <overlay> element in jboss-web.xml has the same outcome as the overlay feature in the CLI: https://docs.jboss.org/author/display/AS72/Deployment+Overlays
> In jboss-web.xml the overlays element is not used to actually overlay existing files but to add files to a deployment. This is confusing and either this should work the same as the CLI or the documentation around the <overlay> element in jboss-web.xml should clearly state this is not the case and that we do not replace artifacts but rather 
> Attached is a proposed patch that fixes this issue.
