SEC-1239: Special characters in JAAS config file location

Given a JaasAuthenticationProvider declared like this:

I get the folowing exception:
java.lang.SecurityException: D:\Tomcat%205.5.23\webapps\myapp\WEB-INF\classes\jaas.config (The system cannot find the path specified)

The problem stems from

• the fact that there is a special character (%20 is "space") in my Tomcat location.
• the way Resouce is converted to String in method private void configureJaasUsingLoop():
  String loginConfigUrl = loginConfig.getURL().toString();

I've converted the Resource to a File before calling getURL() on it. File.get().URL.toString() is encoded differently from the one obtained from Resource.getURL().toString(). More importantly it is compatible with the current behaviour of com.sun.security.auth.login.ConfigFile which just substitutes "/" characters in the URL for the file separator character, before attempting to use it to load the file. I think the problem essentially lies with the behaviour of ConfigFile, but this seems to fix it.
