Project: Solr
Issue Type: Bug
Affects Versions: 4.4
Reporter: Pavel Yaskevich
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}

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?
