Hi guys,

  I'm trying to replace solr.SearchHandler to custom one in solrconfig.xml for one of the stores, and it's throwing following exception: 

{noformat}
Caused by: org.apache.solr.common.SolrException: RequestHandler init failure

I actually tried extending SearchHandler, and implementing SolrRequestHandler as well as extending RequestHandlerBase and it's all the same ClassCastException result...

org.my.solr.index.CustomSearchHandler is definitely in class path and recompiled every retry. 

Maybe I'm doing something terribly wrong?
