whackiness in dispatch filter

[Mark Miller]

In SolrDispatchFilter there is now a parsers field of 

protected final WeakHashMap<SolrConfig, SolrRequestParsers> parsers = 
new WeakHashMap<SolrConfig, SolrRequestParsers>();

It was <SolrCore, SolrRequestParsers> in Solr 1.3. Whats the reason for 
the change? Below, in doFilter we are still actually using SolrCore 
rather than SolrConfig. Offhand I'm not sure why the compiler does not 
complain, but it seems a little odd:

         SolrRequestParsers parser = null;
         parser = parsers.get(core);
         if( parser == null ) {
           parser = new SolrRequestParsers(config);
           parsers.put( core.getSolrConfig(), parser );
         }
