>             Project: WildFly
>          Issue Type: Bug
>          Components: EE
>    Affects Versions: 10.0.0.Final

> It is either bug in how deployments are treated or how overlay/vfs work.
> Steps to reproduce:
> 1. deploy undexploded war with jar inside
> 2. add overlay that will add non existing file in jar
> Result: exception:
> Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS018776: Failed to get content for deployment overlay WEB-INF/lib/overlayed.jar//META-INF/x/file.txt at WEB-INF/lib/overlayed.jar//META-INF/x/file.txt
>     Caused by: java.io.FileNotFoundException: /content/shell.war/WEB-INF/lib/overlayed.jar/META-INF/x/file.txt"}}

>     at org.jboss.as.test.integration.deployment.deploymentoverlay.war.OverlayNonExistingResourceTestCase.testOverlay(OverlayNonExistingResourceTestCase.java:67)
> Expectation:
>  should work. It actually does work, if war is really exploded or
> 'if(exploded)' part in overlay is removed from overlay processor and everything is handled via: https://github.com/stuartwdouglas/wildfly-core/blob/a75af9118c4062fafb899b2c1109387a0748d925/server/src/main/java/org/jboss/as/server/deployment/DeploymentOverlayDeploymentUnitProcessor.java#L117
> This is part of the fix of above issue, which depends on WFCORE-761.
