JCS jcache examples specifically with spring caching

[Tim Cronin]

I'm trying to leverage Spring caching using jcs cache
the javadocs show only ctor for the JCSCachingManager.
https://commons.apache.org/proper/commons-jcs/commons-jcs-jcache/apidocs/src-html/org/apache/commons/jcs/jcache/JCSCachingManager.html#line.83

but i pass in what seems more like default values

public static void main(String[] args) throws Exception
  {
   JCSCachingProvider provider = new JCSCachingProvider();
   Properties props = new Properties();

   CacheManager cacheMgr = new JCSCachingManager(provider,
       JCSCachingProvider.DEFAULT_URI,
       Thread.currentThread().getContextClassLoader(),
       props);

//... do cache stuff...

   cacheMgr.close();

  }

I'm trying to fit this into an existing webapp that uses xml base
configuration
and having to set the defaults seems problematic, I'd have to wrap it to get
proper current class load or use system which doesn't map to webapp loader

Is there any reason for not having a default Ctor?
