/**
 * Shiro uses a context prefix with its resource path {@link ResourceUtils#getInputStreamForPath(String)}. This
 * method allows the inclusion of a system variable within the file path specification, expands the variable, and
 * returns the result in a format suitable for use with Shiro ResourceUtils
 * /*from   w  w  w. j av  a2s  . c o m*/
 * @param resourcePath
 *            a resource path of the form "file:$user.home/directory/filename". If there is no "file:" prefix, or
 *            variable specified, <code>resourcePath</code> is returned unmodified.
 * @return the resourcePath with the system variable expanded. This "file:$user.home/directory/filename" will be
 *         returned, for example as "file:/home/david/directory/filename"
