Using Wildfly 8.2.0.Final, Windows 7, JBoss Developer Studio 8.0.2.GA.
We're trying to split our war into modules. Seems like the most natural way to do this is by relying on web fragments + JSF/Facelet ability to find resources in war/WEB-INF/lib jars.
The problem is that changes to xhtml facelet templates and static resources don't apply on the fly, as it happens if the same things are located in the war itself.
As I understand it's because:
VFS3 User Guide says "Whenever possible the JavaZipFileSystem attempts to use the JarEntry to support file system operations. When this is not possible it will write a copy of the JarEntry to the temporary directory". I don't understand what this "when not possible" means, and stepping through org.wildfly.extension.undertow.deployment.WarStructureDeploymentProcessor code it seems that a jar copy is always made.
