  - ### JarResourceSet

    public JarResourceSet(WebResourceRoot root, String webAppMount, String base, String internalPath) throws IllegalArgumentException
    Creates a new `WebResourceSet` based on a JAR file.
    Parameters:
      `root` - The `WebResourceRoot` this new `WebResourceSet` will be added to.
      `webAppMount` - The path within the web application at which this `WebResourceSet` will be mounted.
      `base` - The absolute path to the JAR file on the file system from which the resources will be served.
      `internalPath` - The path within this new `WebResourceSet` where resources will be served from. E.g. for a resource JAR, this would be "META-INF/resources"
    Throws:
      `IllegalArgumentException` - if the webAppMount or internalPath is not valid (valid paths must start with '/')
