It's Solr+Jetty, also tried using EmbeddedSolrServer with the same result. I 
thought about classloader not picking up the class myself, but if I tell it the 
wrong class it throws expected ClassNotFoundException in Class.forName, where 
with existing class it actually fails in asSubclass method with 
ClassCastException, which means that the custom class was found. 

Looking at the code of SolrResourceLoader.java:443 it has trace in place, I 
will try to run with log level set to trace tomorrow and post results here, 
maybe that will give more clarity...

 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:

 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?

Thanks for the tip [~mkhludnev], putting a handler into war file did help, I'm 
resolving the ticket. Confirmed that I was doing it wrong :)

The same (ClassCastException) happens when I try to extend QueryComponent, I 
don't declare any methods in extending class tho, could that be a problem?

searchComponent name=query class=org.my.solr.index.CustomQueryComponent /

Here is the class definition I use: 

{noformat}
package org.my.solr.index;

import org.apache.solr.handler.component.QueryComponent;

public class CustomQueryComponent extends QueryComponent
{}
{noformat}

It throws following:
