Deployment Overlay feature is not able to replace the application libraries.

    Details

      Description

      -----------------------
      According to the documentation: [1] the deployment overlay feature is applicable for "swapping out deployment descriptors, modifying static web resources to change the branding of an application, or even replacing jar libraries with different versions."

      Here it talks about "replacing jar libraries" which is not working as expected and causes the following error.

      [1] https://docs.jboss.org/author/display/AS72/Deployment+Overlays

      Follow the below sequence of deployment and overlay:
      Steps to Reproduce:
      ------------------
      Step-1). Undeploy if any existing application is deployed and then freshly deploy the application.

      [standalone@localhost:9999 /] undeploy DeploymentOverlayDemo.war
      [standalone@localhost:9999 /] deploy /home/jaysensharma/TestApp/build/DeploymentOverlayDemo.war

      Step-2). Make some changes in java code "Hello.java" . Create a new JAR Hello.jar which we want to replace at (/WEB-INF/lib/Hello.jar) using deployment-overlay feature. In the attached ant based Demo just do "ant compile" to create a new Jar "${project.dir}/tmp/Hello.jar"

      Step-3). Use the following command in order to replace the "/WEB-INF/lib/Hello.jar" with the newly created Hello.jar using deployment overlay feature as following:

      [standalone@localhost:9999 /] deployment-overlay add --name=myOverLay_1 --content=/WEB-INF/lib/Hello.jar=/home/jaysensharma/TestApp/tmp/Hello.jar --deployments=DeploymentOverlayDemo.war --redeploy-affected

      Above causes the following Exception:
