      1. Create a folder in welcome content and create a bad symlink in the folder 
        mkdir folder
cd folder
ln -s xxx bad
      2. Start server standalone.sh
      3. Allow directory listing in file handler 
        /subsystem=undertow/configuration=handler/file=welcome-content:write-attribute(name=directory-listing, value=true)
reload
      4. Go to the folder in welcome content 
        http://127.0.0.1:8080/folder
      Show
      Create a folder in welcome content and create a bad symlink in the folder mkdir folder cd folder ln -s xxx bad Start server standalone.sh Allow directory listing in file handler /subsystem=undertow/configuration=handler/file=welcome-content:write-attribute(name=directory-listing, value= true ) reload Go to the folder in welcome content http: //127.0.0.1:8080/folder

      When I added a bad symlink to the welcome-content and allowed directory-listing in the file handler of the welcome-content server returns Internal Server Error (500) when accessing the folder containing the bad symlink. However, no exception is logged in the output on WildFly.

      I also tried to use simple example application - File Serving from Undertow Examples where I can see the following exception when accessing the directory with the bad symlink:
