[wildfly-dev] Do we support overlay for files in jar of war of ear?

Hi, I am working on https://issues.jboss.org/browse/WFCORE-761 for a while, and I am stuck in the case of overlaying files in jar of war of ear. I want to know that do we support overlay for files in jar of war of ear? like: xx.ear/yy.war/zz.jar/META-INF/config.properties DeploymentOverlayDeploymentUnitProcessor.java[1] and DeferredDeploymentOverlayDeploymentUnitProcessor.java[2] are classes to handle the deployment overlay, but in this case, the jar of war of ear does not get mounted yet, which leads to DeferredDeploymentOverlayDeploymentUnitProcessor.handleEntryWithFileParent() method is called, which just prints the error message. The way to fix it maybe mount the jar(VFS.mountZip) beforehand, but it is specific to the case of ear/war/jar, and these 2 classes are more generic(they are in wildfly-core, no ee nor undertow extension), so where this can be fixed?
