--------------------------------------------
Hoss, the latest patch fixes the issue I noted. Do you still see any problems
with the idea/patch?
> SolrResourceLoader must cache name vs class

> every class that is loaded through SolrResourceLoader does a Class.forName()
> and when if it is not found a ClassNotFoundExcepton is thrown
> Then , it looks up with the various packages and finds the right class if the
> name starts with solr. Considering the fact that we usually use this
> solr.<classname> format we pay too much of a price for this. After every
> lookup the result can be cached in a Map<String,Class> and can be shared
> across all the cores and this Map can be stored at the CoreContainer level
