      Description

      Servlet is provided with VFS mount points to be able to read resources from any library submodule packed in an EAR, but it does not have VirtualFilePermissions to do so when running with Security Manager enabled. This leads to the situation when the parent module corresponding to the EAR deployment does have VirtualFilePermissions to read resources from libraries packed in the deployment, but web submodules cannot reach them. Web submodules are provided only with permissions to its own resources like WEB-INF/classes etc. and they are missing the parent module permissions. See the following stack trace:
