Hi all, I observe some warning stack traces when doing a ".dodeploy"/".undeploy"./".dodeploy" cycle of an exploded JSF application. A sample application is attached to https://community.jboss.org/message/856452 In this forum post, I reported a "locked manifest.mf" file error, so maybe the exceptions are related to this error. To reproduce: extract the zip file content attached to the forum post to the "deployments" directory of a standalone WildFly CR1 server. Create a "KuchenZutatJSF.ear.dodeploy" marker file. After this first ".dodeploy", access the URL http://localhost:8080/KuchenZutatJSFWeb/kuchenliste.faces (that should be enough to reproduce the error). Then create ".undeploy" and ".dodeploy" marker files. Now a warning stacktrace is in console, e.g. this one: 20:55:48,617 INFO [javax.enterprise.resource.webcontainer.jsf.config] (MSC service thread 1-1) Mojarra 2.2.4-jbossorg-1 20131017-1524 für Kontext

related to the "locked files" issue, or is this an Undertow issue?
