Noble Paul commented on SOLR-536:
---------------------------------

Ryan: 
This is expensive
{code:java}
 private final Map<Class, List<DocField>> infocache = 
    Collections.synchronizedMap( new HashMap<Class, List<DocField>>() );
{code}

Let us make it
{code:java}
 private final Map<Class, List<DocField>> infocache = 
    new ConcurrentHashMap<Class, List<DocField>>() ;
{code}

> as we are using java5 .we can use annotations to bind SolrDocument to java 
> beans directly.
> This can make the usage of solrj a  bit simpler
> The QueryResponse class in solrj can have an extra method as follows
> public <T> List<T> getResultBeans(Class<T> klass)
> and the bean can have annotations as
> class MyBean{
> @Field("id") //name is optional
> String id;
> @Field("category")
> List<String> categories
> }
